Robot doesn't respond when i add a fifth motor

[starsROBOTICS]

I programmed 4 CIM motors using jags and i tried adding another motor(Not CIM) to a victor and my robot becomes unresponsive. The code works just fine. I probe the wires and i recieve a value so i know the code works but the robot doesn't respond at all. If i take the fifth motor out of my code the robot works again. Does anyone know why this happens?

Can you show us your code?

Uh not really the code is on the school computer and im at home.

I just hooked up the 5th motor exactly how i did the other motors, the other motors work- i just changed the pwm port and used a differnt button and my entire robot becomes unresponisve.
I can put a picture of the code tomorrow just not today.
