move to a position not being looked at

Ive been trying to move an object to a position, the code below doesnt work correctly though and Ive been at it for some time and cant see just what i'm doing wrong, any suggestions would help;

// get target position Vector3 targetMoveLoc = targetPos.position;

// direction to target Vector3 moveDirection = targetMoveLoc - transform.position;

// move Ccontroller to target position controller.Move(moveDirection.normalized movementSpeed Time.deltaTime);

ideas ?
