expressions on buttons

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
=====================

Try this syntax:

set variable: "/:label" = Eval ("loc"&id&"map")

Then on your button put:

On (Release)
Begin Tell Target ("/address")
Go to and Play (/:label)
End Tell Target
End On

/: refers to the main timeline.

Hope that helps!!

Thanks FlashGuru. Your help is always excellent.

I've been playing around with this most of today. The solution I found was to tell "/address" to goto and play a set label and pass variables to "/address" to make that label behave dynamically, based on what button was pressed.

Looks something like this:

On (Release)
Comment: load a map file (external)
Load Movie ("../media/"&map, 9)
Comment: display one address
Set Variable: "/address/buttonsmap:id" = id
Set Variable: "/address:id" = id
Set Variable: "/address/buttonsmap:url" = url
Set Variable: "/address/buttonsmap:map" = map
Begin Tell Target ("/address")
Go to and Play ("map")
End Tell Target
End On
