Joystick problems

Unity Engine
1

Ok a while back I posted about a circular clamped Joystick, and got it working perfectly. Lately I did some durability testing on it, and found a problem that I can’t seem to fix. I have two joysticks on screen, so if I hold down one, its touchID = 0, and if I then hold down the other one then the other ones touchID = 1, that all works right, but then if I take my finger off of the joystick whose touchID is zero, the other joysticks touchID is supposed to go to zero, and the original one with a touchID of zero is supposed to go to -1, but what happens is both go to -1, and I can’t figure out why. Any help would be greatly appreciated.

EDIT: Fixed Code is Posted Below

Anyone?

Nevermind, I got it fixed, it works perfect now. Heres the final revised code.
