Axis Issue

Hello, I wrote a script for my model for it to move/Jump and whatnot, and am having an issue.

     void Update () {
         Vector3 forward = Input.GetAxis ("Vertical") * transform.TransformDirection (Vector3.up) * MoveSpeed;
         Vector3 jump = Input.GetAxis ("Jump") * transform.TransformDirection (Vector3.forward) * MoveSpeed;
         cc.Move (forward * Time.deltaTime);
         transform.Rotate (0, 0, Input.GetAxis("Horizontal") * RotationSpeed * Time.deltaTime);
         cc.SimpleMove (Physics.gravity);
     }

It is important to note that when I imported my model, the axis were wrong...Therefore, the forward vector does use Up, but that works perfectly. Now, the vector after that, Jump, is my problem. I tested it, and if I use Vector3.forward in the line previous to the this variable, it makes the character jump. However, it literally doesn't do anything in the second line.
