Referencing variable on another timeline

Hi gang,

I’ve got a simple scenario which has been causing some distress and confusion for me. I have a movie clip placed on the stage, which has a variable defined within it. My question is…how can I reference that variable from the _root timeline, without instantiating any on{} statements?

Sounds simple, yes…but I’m unable to do this. I’ve tried setting the variable in a variety of ways (var, global, Object, etc). No matter how that variable is set, I simply cannot reference from the main timeline, without reading the variable in an on statement block

ex.
trace(_root.mcTest.strTest); // invalid

on(press) {
trace(_root.mcTest.strTest); // correct
}

Thanks in advance to anybody who can enlighten me.
