Can Somebody Help Me On Star Wars The Force Unleashed Level!?

I’m playing the Level towards the end where you have to pull the star destroyer into this big cannon. I destroy all the tie fighters and then when I grab the destroyer with the force, the toggle movements show up but they don’t do anything. It tells me, LS up to the left and the Right stick goes up and down but all the star destroyer does is turn. I can’t get it to come closer. WHat am I doing wrong???
