CJ, its probably just easier if we modify your robofile that you have. Can you include it here in a post? We'll have a look and make the needed changes.

Cj,
See the attached robofile that uses the recently released Differential Drive module which makes this process much easier. You will need to download the latest copy for this to work.
Note that you cannot directly connect the Joystick variables which range from -1000 to 1000 to the NXT motors which expect 0 to 255 values. The Differential drive module helps to map these values correctly and translates the joystick movements (vertical/horizontal movement) to motor movements (left and right motors).
Note that motorc is turned on (set to 255) when button 1 is pressed (the If statement does this) and otherwise is set to 128 (neutral).
