Problems with Hit / Drop script

I’m having a problem with something really simple, i basically want to drag and drop the glasses over the area near the eyes and nose (theres an invisible mc there - on layer 6) when that happens i want to fade in the image with the girl with glasses on.

The file is too big to attach so i’ve provided a link to the fla. If anyone could set me straight what i’m doing wrong please.
