Apps Issue with movement in my game.

[glascor]

HI,

I have a shooter game. I can move from left to right but in order to move right I have to press in the far right corner to move to the right. Anywhere else it moves to the left. I am hoping to have it setup at center and if you press to the left or right it will move accordingly.

Any help would be greatly appreciated. The code is listed below.

Thanks,
