A simple code doesn't work!

Inside a movie clip (on a button), i have this:

on (release) {
if (passwordFld == “practice”) {
_root.gotoAndStop(“level1”, 1);
}
}

and it doesn’t want to move to that frame. If i put trace or mouse hide or anything else, it works. It just won’t move to the chosen frame!! Why?! (scene name is ok!)
