Somethings wrong with my _root

ive searched the forums, and google, and nothing seems to be wrong:

[AS]on (rollOver) {
_root.oldman.gotoAndPlay(“1”);
}
[/AS]

the buttons are in their own movie clip, and so is oldman… i just cant figure it out :h:

thanks in advance

UUUURRRRRRRGGGGGGGGGGG!!!

Basically:

_root = First timeline in the hierarchy

_parent = 1 timeline up in the hierarchy from the timeline you are currently on

this = timeline you are currently on
