[fmx] adressing

A problem accured, I believe i have the adressing wrong, but don’t know how to solve it.

I have a movieClip, in it a button, in it another movieClip (activated on mouse over). When i rollOver it works normally, it stops at the 15th frame as it should. Now I have another 15 frames for the rollOut and i can’t get them to play,

on(rollOut) {
_root.spin.contact.contact_mc.gotoAndPlay(16);
}

(or)

on(rollOut) {
this.contact_mc.gotoAndPlay(“mark”);
}

legend:
spin -> main movieClip
contact -> button in it
contact_mc -> the clip in the button (gives the button the animation)

thx
