Simple Button Dilema but I can't figure it out

Hey! I have a menu, with mcs being used as the navigation. Inside one of the mcs however are actual buttons, that i’d like the visitor to be able to click to go to a different URL. But i can’t get them to work. I know its a target problem, as taking them out of the MC and putting them on the main stage of course they work, but i can’t figure out the correct target to get them to work from inside the mc. I’ve used:
on (release) {
this._parent.getURL(
“neck.html”);

}

and of course also tried simply _root and _parent in different attempts as well and still the buttons wont work from inside the MC - any one have any ideas what I’m doing wrong? (I tried a search on the forum but didn’t see this one) I’m sure it’s something simple but i guess i’ve been staring at this for too long and don’t see it at the moment. Any help would be greatly appreciated! Thanks!
