Dual action on buttons

I used this code in a button:

on (release) {
gotoAndPlay(“primero”);
_root.navegador.gotoAndPlay(“start”);
}

the button when released has to play the label “primero”
and then go to the root, find a clip called “navegador” and play the label start.

flash tells me the script has no errors, but he button does not work.

any ideas???

i’m not 100% sure, but try parent instead of root.
