Can't see movie clip

Hi, just joined your forum having never done AS before.
I started a degree in computing with multimedia technologies in September (2009) and for an assignment we are required to make a game.

I have made the game but I can’t see the movie clip called ‘Bolt’ when I run it. I know its set to -15 to start with but its supposed to move down and it doesnt!

Im convinced (for reasons unknown to myself) that its in Flash rather than AS, probably because there are no errors.

I know its going to be something silly and stupid but I just dont know what it is and its driving me mad!

I would be so grateful if you could help or point me in the right direction.

Thank you in anticiption,
Luci

p.s files attached but wont let me upload .fla as its too big
