Update: we achieved strafing and forward/backward, but rotation is not working, the front motors run forwards and the back backwards, or vice-versa based on direction of rotation, so that all motors are pulling outward and are fighting each other, the wheels are arranged in the proper X-formation, we arranged our input values and everything else is functioning properly, here is the code we used that fixed the problem:

We also used this link to setup or rotation values:
