Trash can for dupes

I have made a application where users can select an object, which duplicates and then can be dragged and dropped (leaving the original). Now, I want to add a trash can function to the whole thing. Here is the script it all.
on (press) {
if (this._name.substr(0, 4) != “dupe”) {
root.int_bldCnt++;
var str_trgName = "dupe
"+_root.int_bldCnt++;
this.duplicateMovieClip(str_trgName, _root.int_bldCnt);
} else {
var str_trgName = this._name;
}
_root[str_trgName].startDrag(true);
}
on (release, releaseOutside) {
stopDrag();
if (this.droptarget == “_level0.trashcan”) {
this.removeMovieClip();
}
}
The _level0.trashcan part is not working. Help anyone? skee
