Please Help, Bullet direction

Hello, i am creating a game wer bullets are fired from an arrow at the bottom of the screen. I have been trying to get the bullets move in the same direction as the arrow is facing when fired. I have the arrow_rotation output to the screen but I am unsure how to use this to set the duplicate movie clip direction. Any Ideas? I have attached the fla for you guys to look at :smiley: Thanks, Phil
