tennis game glitch, can not find it in the code.

[cyberclaw2000]

oke so i made a tennis game.

but somehow when i start the game it will not bounce back the ball for the first time, and for as long as the player does not hit the ball, the cpu wont move either.

so score would always be with starting 1-1.
can someone help me with this?
