Forums Scripts & Popups Return variable position?

I'm trying to find the position of a variable i want.

I know it has certain characters in it al the time but it always is on a different position.

As i normaly would do tokenize 32 $strip($1-) and mark position as $5 for example it now fails.

on *:TEXT:*:#:{
tokenize 32 $strip($1-)
if ($regex($1-,/(.*?)\-/i) > 0) {
var %location = ?
}
}

Another thing, as i just copy-pasted the regex, if anyone can explain what this means?
($regex($1-,/(.*?)\-/i) > 0)
