Hi you flash 5 actionscript experts around the world!

How can I adress a _level with a variable?

Expl: I like to define a variable n to adress a movie on _level n. but I don't know the syntax. (I only know the syntax for movieClips that is for example _level0["clip"+n]._x = ... and ["_level"+n].clip2 = ... doesn't work)

I'll bake a cake for anyone with a helpful answer and send it even to brasilia if that answer would do the trick. HELP!
