Need a littile help with this script -->

I need this script to run, but I gues I’m no so good with actionscript and making stupid mistakes. Anyway, heres the script I have problems with:

on (press) {
startDrag(_target);
}
on (release) {
stopDrag();
this._x = 592;
this._y = 549.5;
if (this._droptarget == “/for_r”) {
eval(this._droptarget.gotoandplay(2));
} else {
eval(this._droptarget.gotoandplay(3));
}
}

The idea is simple: if the movie clip I drag falls on on a movie clip named “for_r”, “for_i” changes to frame 2, if it isn’t my “for_i”, some other clip changes to frame 3.
Please help!
