I don't understand - I have following function on my main timeline
this.my_mc.myMov_mc.test_btn.onRollOver = function(){
trace(this);};

When test_btn start at frame 1 it wotks but when it starts at ex. frame 10 it
don't works.
Can you explain that?

Hi,

If you put your button on frame 10, then to Flash it doesn't exist when you
run your code on frame 1. To fix this, you could either put the code on frame
10 or later, of hide the button (button._visible = false) until you need it.

Hope this helps
