gotoAndPlay error :( (I'm sorry, I can't get it!)

Hi,
I have been trying to make characters on the screen run away when I fire the first shot from my gun.

I have a timeline within the movieclip with all of the animation frames. The first 5 frames are the standing/walking animation, which loop until the gun is fired and then the run animation is implemented.

I got the characters to “move” away, but they arent animated
When the shot is fired I want the movieclip to play. starting at frame 6 until then end up of the total amount of frames.

I have a Boolean variable setup to show that it is true when the mouse is down(and remains true), the only problem is, it continues to loop and play frame 6 REPEATEDLY, appearing as if the animation is locked.

I was wondering how I would go about making a Boolean variable that would allow me to play through all of the frames, and not just frame 6. I.E. Only calling the gotoAndPlay command once, instead of every frame that the game is played.

Can someone please help me, I’m sure this is a very noob question to you, but I cannot figure it out and this same problems applies to other parts of my game as well.

Any help will be greatly appreciated,
Scheisse
