Ps4 controlled arduino car kit

Hello everyone (and those who have been following my previous threads), today we have received the parts missing from the previous tread and got the arduino to communicate with the bluetooth usb Dongle. Set up went flawlessly and the no problems with the serial monitor. The problem? The motors won't move when moving the joystick on my controller but the piezo buzzer makes a sound indicating the code is functioning properly. If any additional information is needed please view my previous threads, I tend to leave as much information as possible in the first comment of each thread.
