ocular rewritten

The idea of (x) - (scroll x) has always worked for me. I am making a top down shooter, and the player head and the arms and gun are in different sprites. I need the arms to go to the player, and I did go to x: (item (i) of player x) - (scroll x) / (camera scale) and the same for y, but the arms do not stay with the player. They are close, but are just slightly slower than the player. Anyone know how to fix this?
