Can you post a screen shot of your Begin.vi and Teleop.vi? I suspect your problem is in one of these two.

Probably, you haven't initialized your drive correctly in some fashion. You need to invert motors you haven't or some such. Things to make sure of and try:
1. Your signal wiring is correct. The PWM for the Left Front Motor is connected to the Jag for the left front motor, and so on.
2. Your power wiring is correct. You really, really just want to connect the red wire of each motor to its corresponding M+ terminal. Black wire to the M- terminal. Do this for ALL your motors, fix direction problems in software.
3. After 1 and 2, check motors individually. Unplug the PWMs so that you're only running one motor per side. Wiggle joystick and check responses. Now replug/unplug PWMs to run the other two motors, still one motor per side. Wiggle joystick. If you've done 1 and 2, then you should see which motors aren't responding like you expect, and those motors likely need to be inverted in your Begin.vi code.
