Ok, why is this not working?

[Illyahr]

Doing some code and, as far as I can tell, it all works. However, it keeps coming back wrong.

var stat as string
var bonus as number
var trunc as number
stat = hero.child[cHelpStk].tagids[User.a?]

Comes back as "User.aWIS" (it can be changed later, hence the code)

trunc = length(stat)-5
stat = right(stat,trunc)

Comes back as "aWIS"

stat = "#attrmod[" & stat & "]"

Comes back as "#attrmod[aWIS]"

bonus = stat

Comes back as 0. Actually putting the stat in comes back correctly, but not if I use the script.
