I have been discussing this macro in another site: &{template:default}{{name=Soul check}}{{ [[ {1d20+6}>[[?{Spell level} + 12]] ]] Success }} The macro is for a DnD 5e variant, spells are powered by souls and if you blow a soul check you lose the soul you were using. The DC is 12+spell level, the relevant bonus in this case is +6. Apparently, someone tried this macro and found that it doesn't do the comparison properly. I tried changing it to {{ [[ {1d1+6}>[[?{Spell level} + 1]] ]] Success }} A nd that one worked. I'm on Firefox. Is there some browser-specific bug going on?
