Another Divine Smite Question

I have been at this for hours. I have read every thread I could find, copied and used bits of every post I could find that had an example, and I still am unable to get a result. Can someone please help me see what I need to change on this macro... &{template:dmg} {{rname=Divine Smite}} {{range=Melee}} {{damage=1}} {{dmg1flag=1}} {{dmg1=[[ ((?{Spellslot|1st lvl,2|2nd lvl,3|3rd lvl,4|4th lvl,5|5th lvl,5} + ?{Undead/Fiend|No,0|Yes,1}) * ?{Crit|Yes,2|No,1})d8ro<2}} ]]}}  {{dmg1type=Necrotic}} {{desc=Smite Thy Foe}} I cannot tell you how appreciative I'll be. Thank you!

It would help to know what's going wrong (and which sheet youre using). I tested this with the default rolltemplate (just changing template:dmg to template:default)  and it seems to work fine. so the damage in dmg1 works properly. I dont know the other flags do.

Thank you! You'r einput plus finding a new example that showed me what I was missing. I got it now. &{template:5eDefault} {{title=Devine Smite }} {{subheader=@{Gadelha|character_name}}} {{subheaderright=Smite Thy Foe}}  {{rollname=Necrotic Dmg}} {{roll=[[ ((?{Spellslot|1st lvl,2|2nd lvl,3|3rd lvl,4|4th lvl,5|5th lvl,5} + ?{Undead/Fiend|No,0|Yes,1}) * ?{Crit|Yes,2|No,1})d8ro<2 ]]}}

Great!
