Node Won't Move with chase camera

Troubleshooting
1

Hi all,

I’m taking a Game Design course where we are supposed to modify the game code to allow for character movement based on a chase cam. I can’t for the life of me figure out why the character doesn’t move, but instead has his animation in place. Can anyone take a look at this and point me in the right direction? Thanks.
