so how come you don't unset them global vars?

imho this snippet looks like it was tossed together in 1 second with no thought.

why don't you spend some time on this and get rid of all them global vars as well as maybe make it so they can only vote once among other things.. like don't have regular users be able to unset/set surveys
Also whats the point of this line?

if ($1 == .lines) { msg $chan There are 14 lines in this script. }

Take some time and..
um keep working on it.....

you seem to have a typo on this line as well

if ($1 == .total) { | msg $chan A: %surveya | msg $chan B: %surveyb | msg $chan C: %surveyc }
