Problem with an Attack Macro

I'm trying my hand at creating my first macro for Roll 20 5e but I have an issue with an error could it be the  Vicious Mockery /em uses @{Sligh Da Miser|repeating_attack_$0_atkname} to attack @{selected|wtype}&{template:simple} {{name=Weapon Spell Attack}} ?{Attack   | repeating_attack_$0_atkname,          {{rname=️repeating_attack_$0_atkname}}       @{wtype}&{template:atkdmg} {{mod=@{repeating_attack_$0_atkbonus}}} {{rname=@{repeating_attack_$0_atkname}}} {{r1=[[@{repeating_attack_$0_hidden_r1base}@{halflingluck}cs>@{repeating_attack_$0_atkcritrange}@{repeating_attack_$0_hidden_atkbonus}]]}} @{repeating_attack_$0_hidden_r2base}@{halflingluck}cs>@{repeating_attack_$0_atkcritrange}@{repeating_attack_$0_hidden_atkbonus}]]}} @{repeating_attack_$0_atkflag} {{range=@{repeating_attack_$0_atkrange}}} @{repeating_attack_$0_dmgflag} {{dmg1=[[@{repeating_attack_$0_hidden_dmg1}]]}} {{dmg1type=@{repeating_attack_$0_hidden_dmg1type}}} @{repeating_attack_$0_dmg2flag} {{dmg2=[[@{repeating_attack_$0_hidden_dmg2}]]}} {{dmg2type=@{repeating_attack_$0_hidden_dmg2type}}} {{crit1=[[@{repeating_attack_$0_hidden_crit1}]]}} {{crit2=[[@{repeating_attack_$0_hidden_crit2}]]}} @{repeating_attack_$0_saveflag} {{desc=@{repeating_attack_$0_atk_desc}}} @{repeating_attack_$0_hldmg} @{repeating_attack_$0_spelllevel} ammo=@{repeating_attack_$0_ammo} @{charname_output}   | repeating_attack_$1_atkname,          {{rname=repeating_attack_$1_atkname}}         @{wtype}&{template:atkdmg} {{mod=@{repeating_attack_$1_atkbonus}}} {{rname=@{repeating_attack_$1_atkname}}} {{r1=[[@{repeating_attack_$1_hidden_r1base}@{halflingluck}cs>@{repeating_attack_$1_atkcritrange}@{repeating_attack_$1_hidden_atkbonus}]]}} @{repeating_attack_$1_hidden_r2base}@{halflingluck}cs>@{repeating_attack_$1_atkcritrange}@{repeating_attack_$1_hidden_atkbonus}]]}} @{repeating_attack_$1_atkflag} {{range=@{repeating_attack_$1_atkrange}}} @{repeating_attack_$1_dmgflag} {{dmg1=[[@{repeating_attack_$1_hidden_dmg1}]]}} {{dmg1type=@{repeating_attack_$1_hidden_dmg1type}}} @{repeating_attack_$1_dmg2flag} {{dmg2=[[@{repeating_attack_$1_hidden_dmg2}]]}} {{dmg2type=@{repeating_attack_$1_hidden_dmg2type}}} {{crit1=[[@{repeating_attack_$1_hidden_crit1}]]}} {{crit2=[[@{repeating_attack_$1_hidden_crit2}]]}} @{repeating_attack_$1_saveflag} {{desc=@{repeating_attack_$1_atk_desc}}} @{repeating_attack_$1_hldmg} @{repeating_attack_$1_spelllevel} ammo=@{repeating_attack_$1_ammo} @{charname_output}   | repeating_attack_$2_atkname,          {{rname=repeating_attack_$2_atkname}}         @{wtype}&{template:atkdmg} {{mod=@{repeating_attack_$2_atkbonus}}} {{rname=@{repeating_attack_$2_atkname}}} {{r1=[[@{repeating_attack_$2_hidden_r1base}@{halflingluck}cs>@{repeating_attack_$2_atkcritrange}@{repeating_attack_$2_hidden_atkbonus}]]}} @{repeating_attack_$2_hidden_r2base}@{halflingluck}cs>@{repeating_attack_$2_atkcritrange}@{repeating_attack_$2_hidden_atkbonus}]]}} @{repeating_attack_$2_atkflag} {{range=@{repeating_attack_$2_atkrange}}} @{repeating_attack_$2_dmgflag} {{dmg1=[[@{repeating_attack_$2_hidden_dmg1}]]}} {{dmg1type=@{repeating_attack_$2_hidden_dmg1type}}} @{repeating_attack_$2_dmg2flag} {{dmg2=[[@{repeating_attack_$2_hidden_dmg2}]]}} {{dmg2type=@{repeating_attack_$2_hidden_dmg2type}}} {{crit1=[[@{repeating_attack_$2_hidden_crit1}]]}} {{crit2=[[@{repeating_attack_$2_hidden_crit2}]]}} @{repeating_attack_$2_saveflag} {{desc=@{repeating_attack_$2_atk_desc}}} @{repeating_attack_$2_hldmg} @{repeating_attack_$2_spelllevel} ammo=@{repeating_attack_$2_ammo} @{charname_output}   | repeating_attack_$3_atkname,          {{rname=️repeating_attack_$3_atkname}}         @{wtype}&{template:atkdmg} {{mod=@{repeating_attack_$3_atkbonus}}} {{rname=@{repeating_attack_$3_atkname}}} {{r1=[[@{repeating_attack_$3_hidden_r1base}@{halflingluck}cs>@{repeating_attack_$3_atkcritrange}@{repeating_attack_$3_hidden_atkbonus}]]}} @{repeating_attack_$3_hidden_r2base}@{halflingluck}cs>@{repeating_attack_$3_atkcritrange}@{repeating_attack_$3_hidden_atkbonus}]]}} @{repeating_attack_$3_atkflag} {{range=@{repeating_attack_$3_atkrange}}} @{repeating_attack_$3_dmgflag} {{dmg1=[[@{repeating_attack_$3_hidden_dmg1}]]}} {{dmg1type=@{repeating_attack_$3_hidden_dmg1type}}} @{repeating_attack_$3_dmg2flag} {{dmg2=[[@{repeating_attack_$3_hidden_dmg2}]]}} {{dmg2type=@{repeating_attack_$3_hidden_dmg2type}}} {{crit1=[[@{repeating_attack_$3_hidden_crit1}]]}} {{crit2=[[@{repeating_attack_$3_hidden_crit2}]]}} @{repeating_attack_$3_saveflag} {{desc=@{repeating_attack_$3_atk_desc}}} @{repeating_attack_$3_hldmg} @{repeating_attack_$3_spelllevel} ammo=@{repeating_attack_$3_ammo} @{charname_output}  } I have one error TypeError: Cannot read property 'substring' of undefined Light Crossbow Dagger Vicious Mockery Eldritch Blast

That error usually comes from not defining where the attributes are being called from, have you set this up as a character ability or as a collections macro (if the latter then you need to specify a character either by hardcoding '@{Bob|attribute}' or using @{selected|... or @{target|... to use a token, that token also needs to 'represent' a journal).

I see it in the Macro's area, "In Bar", the character token is selected  the code has this @{Sligh Da Miser does it have to be in each ability? The Token is controlled by a character in the journal and the token is selected I have grabbed other users Marcos, Skill Checks, Saving Throws, Stat Checks, etc.. all work, but trying to get the macro for attacks and damage

Install the Universal Chat Menu API and use this macro; no more need to fix things when they level up!  !chatmenu @{selected|character_id} {template:npcaction}{{rname=@{selected|character_name}}}{{description=CHATMENU}} --separator: |  --title:Attacks --repeating_attack|atkname|attack

Here is for Cantrips and Spells as well Cantrips: !chatmenu @{selected|character_id} {template:npcaction}{{rname=@{selected|character_name}}}{{description=CHATMENU}} --separator: |  --title: Cantrips --repeating_spell-cantrip|spellname|spell Spells: !chatmenu @{selected|character_id} {template:npcaction}{{rname=@{selected|character_name}}}{{description=CHATMENU}} --separator: |  --title: Level 1 Spells --repeating_spell-1|spellname|spell (for spells make separate macros for each level by changing the "spell-1" to "spell-[level]"; just insert number accordingly.  and a bonus Traits: !chatmenu @{selected|character_id} {template:npcaction}{{rname=@{selected|character_name}}}{{description=CHATMENU}} --separator: |  --title:Traits --repeating_npctrait|name|desc= --title:Actions --repeating_npcaction|name|npc_action --title:Traits --repeating_traits|name|output
