camera code and driving

[seanl]

i loaded the bells and whistles version on to our robot and the camera worked perfectly but we could not drive it.the motors just stood there the speed controllers are fine i checked and the pwm was preset on the code to 13-16, i tried it on those and tried changing it on the code to 1-2 and moved the camera pan and tilt to 7-8, this way the camera still worked and the driving didnt. the only thing i could think of is autonomous activating because we only have the camera code on there and nothing about driving. if this is the problem can some one tell me how to fix it. i am stumped on this one.
