Linkage Problem between MCs

Guys,

I like to link MC “A” to MC “B”, however A is located within several MCs and B is located on the main timeline on a label called “Services”.

Now when calling

on (release) {
this._parent._parent.gotoAndPlay(“services”) {
}

it works but I only come to the main timeline and label “Services”

I tried this but it doesn’t work.

on (release) {
this._parent._parent.contentServicesMC.gotoAndPlay(3) {
}

Any tips how to goto different keyframes from MC A ?

Thanks
Dave
