Action for a draggable button with droptarget

I have a draggable button , and I need to go to “scene1” when the draggable button is dropped into a droptarget (“dentro1”)
But it doesn´t work with this action (gotoAndPlay), it works with load movie, or get Url. It only goes inside de droptarget (called “dentro1”)

This is the code of the draggable button:

on (rollOver) {
startDrag(root_draggablebutton, true);
}
on (release) {
if (_droptarget eq “/dentro1”) {
{
gotoAndPlay(“scene1”, 1);
}
}
stopDrag();
}

thank you
