Simply remove any comma in the string when making the calculation :
on *:TEXT:!calc ?*:#test:notice $nick $2- =7 $calc($remove($2-,$chr(44)))
I also edited the code so you should be able to use space like "5 + 6"
I need the comas as well to work, cause many people in my channel use comas in their calculation.
Ah thanks Wims worked like a charm.I'd be greatfull if i could get comas in my answer as well .Removing comas is a great idea
,but i'd appreciate it if i could keep them in the answers
