I'm using the following macro (based off the default ones in the sheet) which I hoped, would let me choose a PC or NPC and cause them to make a saving throw secretly to the GM. /w gm &{template:DnD35StdRoll} {{saveflag=true}} {{name=@{target|token_name} }} {{subtags=braces against the attack}} {{check=Fortitude save:}} {{checkroll=[[1d20 + [[@{fortitude}]] ]] }} {{notes=@{fortitudenote} }} I keep getting this error: "TypeError: Cannot read property 'substring' of undefined" I'm not sure why this wouldn't be working... it's probably just another moment of "I don't understand this coding language"...
