Hi,  
I’m sure this is a simple problem, but I haven’t worked with flash AS3 for this long- and moreover haven’t worked with Flash in almost 2 years.

anyway- from what I hear, using \_root is a bad idea (not sure why).

So have a button, inside an mc1 which when clicked it plays

[TweenLite.to(mc2, 2, {frame:1});]

inside mc2 -which located back on the stage.

Currently I get the error of "access of undefined property)

Thanks
