Enabled not working

ok so basically I want to target a parent mc and disable it from within a nested mc but I cant even figure out how to disable it from the parent timeline.

the clip instance is called tips and I have tried

tips.enabled = false;
and
tips.mouseEnabled =false;

with no luck

the actual tips movie clip has no children but I even tried mouseChildren = false;

Any clues would be great
Thanks Guys.

.parent

tips.parent.enabled=false;

perhaps, im not sure, but parent/child are keywords, check api

What do you actually want to disable? Just the mouseEvents? Is the clip just a movieclip, or a button? or something more useful?
