ActionScript 2.0 :: Using A Simple Function To Display A Button?

create a button, create a movie clip with two frames.

place a button instance in frame 2.

place a mc instance on the stage.

create another instance of the button to change the movie clip instance to frame two.

the button in the movie clip is pressed and executes a function.

here's the code

Code:
// create the button to show the button!
_root.button_instance_2.onPress = function() {
buttonClick1();

[Code].....

if, however, i use the same code on a movie clip that has only one frame it will work fine. do i need to tell the function to target the button instance any more specifically than that?
