Help with actionscript3 in animate

[Alex30519148ezkn]

Hello i am trying to use actionscript 3 to make pretty much a small interactive menu . in the below code i am trying to make it do that when mouse down go from this movie clip to frame 3 and stop but also i want it to go to a different movie clip and stop it at frame 1. I am new to actionscript. both of these are inside of a 3rd movie clip

stop();

this.addEventListener(MouseEvent.MOUSE_DOWN, move);

function move(event:MouseEvent): void {

gotoAndStop(3);

MovieClip(root).Menugoside_mc.findus_mc.gotoAndStop(1);

}

this is the code i am working with but it doesnt make the findus movie clip go to frame 1

Hi.

Does the main timeline go to frame 3 when you click? if so, is there a Menugoside_mc instance in frame 3?

Please let us know.

does MovieClip(root).Menugoside_mc.findus_mc exist when mousedown?  ie, do you see an error when you mousedown?
