gotoAndPlay problem

I want to link a button in my main timeline to a label- frame in a movie clip. The movie clip is called “Adetail” and the label is “on01”…

I type in the following script

on(release){
gotoAndPlay(“on01”)
}

but it doesn’t work…
i’ve also tried

on(release){
_root.Adetail.gotoAndPlay(“on01”)
}

and
on(release){
_root.gotoAndPlay(“on01”)
}

but none of them work. Plz help.
