Robot Runs in full Reverse

[EHaskins]

I am using the camera code from kevin's website and have modified it alot, i have been using the Arcade 1-Joystick drive that is commented out in the defult
code. My problem started when i tried to switch two a Two Joystick drive system. My problem is the robot runs in full reverse. So i made my Program print the values from p1_y, p2_y, pwm03, and pwm04(the drive pwms). But what confuses me is the p1_y and p2_y print as 127 when the joystick is centered but pwm01 and pwm02 = 0. if i move the joystick the pwm values do not change. My code is below:

pwm03 = Limit_Max(p1_y);
pwm04 = Limit_Max(p2_y);

my 1 joystick code is below:

pwm03 = Limit_Max(p1_x + p1_y - 127);
pwm04 = Limit_Max(p1_x - p1_y + 127);

Can anybody help?
