Anybody knowing flash can help me out with this...

I have done a series of plain animation without writing codes(mainly motion tweens and stuff like that). I finally arrive at 4 btns that I have created and also anmated them. The buttons are coming at the last part of the animation, viz., ~130th frame.

As far as I know, while writing a code for the animation, its recommended to open a new layer and write a code in it.

I want to change the alpha settings etc, when moused over. It can be only done with the script alongwith. All the 4 buttons stop at same frame. I have given them distinct kinda names in all sense(instance, layers, library).

Now,When I open a new layer and put in my code in there, the code is being implemented to the first frame of the whole animation only and not on the frame that I want to. No matter, how hard I try, I always can't make the Actions to come onto the frame that I want. And hence, what I write is not being implemented actually.

I know its being implemented to the first frame only, bcos, if I write a stop function, the animation stops itself at the first frame.

Now, I need to know, how to apply actions(code) to a particular frame only?

Note: I am using Actionscript 3.0
