Hi there, I am just getting into the meat of how to properly utilize PowerCards for my games, and I ran into an issue I can't resolve. I am trying to expand on the example used in the "PowerCards : Templates and Replacements" Tutorial video, adding some logic to display misses, hits, and crits. I started by making sure the base PowerCard Worked, which it does: !power {{ --name|@{selected|character_name} - Quarterstaff Attack --Attack Roll:|[[ [$Atk] 1d20 + @{selected|strength_mod} [STR] + @{selected|pb} [PROF] ]] vs @{target|character_name}'s @{target|AC} AC --?? $Atk < @{target|AC}?? Damage:|Missed! --?? $Atk > @{target|AC}?? Damage:|[[ [$Dmg] 1d6 + @{selected|strength_mod} [STR] ]] Bludgeoning --?? $Atk.base = 20?? Crit!:|[[ [$Crit] 2d6 + @{selected|strength_mod} [STR] ]] Bludgeoning }} Which is exactly what I want So i then wrote it as a template, and made the templated macro to follow ( Variable key will be right above that, to easier reading ) 0 - Character Name | @{selected|character_name} 1 - Weapon | Quarterstaff 2 - Ability Modifier | @{selected|strength_mod} 3 - Ability | STR 4 - Proficiency Bonus | @{selected|pb} 5 - Target's Name | @{target|character_name} 6 - Target AC | @{target|AC} 7 - Damage | 1d6 8 - Crit Damage | 2d6 9 - Damage Type | bludgeoning Also, I put it on multiple lines for better reading while editing, I remove newline characters before adding into roll20 # PowerCard Templates Handout WeaponAttack:--name|~0! - ~1! Attack --Attack Roll:|[[ [$Atk] 1d20 + ~2! [~3!] + ~4! [PROF] ]] vs ~5!'s ~6! AC --?? $Atk < @{target|AC}?? Damage:|Missed! --?? $Atk > @{target|AC}?? Damage:|[[ [$Dmg] ~7! + ~2! [~3!] ]] ~9! --?? $Atk.base = 20?? Crit!:|[[ [$Crit] ~8! + ~2! [~3!] ]] ~9! # 04-QuarterStaff-Template Macro !power {{ --template|WeaponAttack|@{selected|character_name};Quarterstaff;@{selected|strength_mod};STR;@{selected|pb};@{target|AC};1d6;2d6;bludgeoning }} When I run this, I get an error on the script that causes it to crash: TypeError: Cannot read property '0' of null
