I'm having some trouble with expressions on buttons.

I need to Eval the name of a label and then Tell Target a movie clip to goto and play the label.

Nothing is working. Can someone please shed some light?
=====================
[I'm setting the id var from a different movieclip.]

set var: label = Eval ("loc"&id&"map")
On (Release)
Begin Tell Target ("/address")
Go to and Play (label)
End Tell Target
End On
=====================
