Death screen - I'm stumped

Please could somebody help, this has stumped me. It should be relatively simple, but it just doesn’t work. I have a turret mc with a health variable inside and when that health variable = 0 then it should turre.gotoAndPlay(10) but it goes to and stops, and i can’t figure it out, can anyone help? Any help would be greatly appreciated. the fla is too big (even zipped) to send, but if you could please help, pm me with your email and i will email the .fla to you.
