I am attempting to get the trained skills that have 0 skill ranks in them to return 0, the macro examples shows: /w gm ?{Trained Skills| Disable Device, Disable Device [[1d20 + @{selected|Disable-Device} *ceil(@{selected|Disable-Device-Ranks}/100)] ]|} as the syntax. I cannot for the life of me get it to operate correctly. It's also not applying the math correctly, it's adding negative numbers. when goofing around I found that: /w gm ?{Trained Skills| Disable Device, Disable Device [[1d20 + @{selected|Disable-Device} ** ceil(@{selected|Disable-Device-Ranks}/100) ]]|} SEEMS to return the appropriate result, including the addition. Syntax says that is an exponent symbol... I'm confused. and adding this line: Spellcraft, Spellcraft [[1d20 + @{selected|Spellcraft} ** ceil(@{selected|Spellcraft-ranks}/100)]]| with 0 points applied, (it should return 0) it rolled a 12 and output 13... This is the full macro I'm putting together. Every other skill returns 0 sans Spellcraft. /w gm ?{Trained Skills| Disable Device, Disable Device [[1d20 + @{selected|Disable-Device} ** ceil(@{selected|Disable-Device-ranks}/100)]]| Handle Animal, Handle Animal [[1d20 + @{selected|Handle-Animal}** ceil(@{selected|Handle-Animal-ranks}/100)]]| @{selected|Profession-Name}, @{selected|Profession-Name} [[1d20 + @{selected|Profession}** ceil(@{selected|Profession-ranks}/100)]]| Sleight of Hand, Sleight of Hand [[1d20 + (@{selected|Sleight-Of-Hand}** ceil(@{selected|Sleight of Hand-ranks}/100)]]| Spellcraft, Spellcraft [[1d20 + @{selected|Spellcraft} ** ceil(@{selected|Spellcraft-ranks}/100)]]| Use Magic Device, Use Magic Device [[1d20 + @{selected|Use-Magic-Device} ** ceil(@{selected|Use-Magic-Device-ranks}/100)]]|} And, moving through my other players character tokens returns different results on all of them. I am really stumped. I am using Pathfinder Community Sheet.
