submenu buttons and rollout effect

[SacTownVlad]

I have a button with rollover effect:
on (rollOver) {
//Movieclip GotoAndPlay Behavior
this.gotoAndPlay("s1");
//End Behavior
}
on (rollOut) {
//Movieclip GotoAndPlay Behavior
this.gotoAndPlay("s2");
//End Behavior
}
on (releaseOutside) {
//Movieclip GotoAndPlay Behavior
this.gotoAndPlay("s2");
//End Behavior
}

On rollover I created movie clip with sub buttons, submenu effect working,
but when I started linking web pages to sub buttons it wont work.
I had to extend hit area for button so rollout effect wont start and supbuttons appear under hit area of original button, I didn’t know that buttons is Flash CS3 cant overlap.
So question is how do I create working buttons with subbuttons and rollout effect.

Thank you for your help.

i think if I move rollout effect script from actual buttons to new button with hit area around actual buttons and subB so I would keep my rollout affect and my buttons wont overlap.

Is there an easier way to do this?
