javascript to c# problem

Hi, I found this script around here about third person control and when I try to convert it to c# it's not working.

 var moveVectorX : Vector3 = theCamera.forward * inputY;
 var moveVectorY : Vector3 = theCamera.right * inputX;
 var moveVector : Vector3 = ( moveVectorX + moveVectorY ).normalized * movementSpeed * Time.deltaTime;
      
 myTransform.position = myTransform.position + Vector3( moveVector.x, 0.0, moveVector.z );
      
 myTransform.LookAt( myTransform.position + Vector3( moveVector.x, 0.0, moveVector.z ) );

and this is what i come up with.

 Vector3 moveVectorX = mainCamera.forward * inputY;
 Vector3 moveVectorY = mainCamera.right * inputX;
 Vector3 moveVector = (moveVectorX + moveVectorY).normalized * moveSpeed * Time.deltaTime;
 
 transform.position = transform.position + Vector3 (moveVector.x, 0f, moveVector.z);
 transform.LookAt (transform.position + Vector3 (moveVector.x, 0f, moveVector.z));
