So the following macro doesn't work and I don't know why... Macro: attack /roll d20+ @{BASE attack bonus} + @{WeaponBonus} + @{StrengthMod} Every time I do this I get the following reply: TypeError: Cannot call method 'toLowerCase' of undefined Doesn't quite make sense to me.. I already double checked the spelling of the attributes. I program for a living so I normally feel pretty smart when it comes to this stuff.. But I don't really have this one figured out. Lemme know if you can help at all
