Try using %variable% rather than variable. My understanding is that % pulls the value out of the variable.

I'm also amused because I spend half my time on the ahk forums telling people that if they want to box they really should come here, and now that you've come here I'm going to say "if you persist in using AHK rather than a good program (like isboxer), its best to ask those questions on the ahk forum."

Most people here haven't used ahk and its considered pretty obsolete. I use it for a lot of things at work and its a godsend, but for multiboxing the $3 a month I spend on isboxer is well worth it.
