Issues with Colour corrector pixels code.

My code includes 6 buttons which work fine, however when I try to attach something to the mouse clicks it never works. I am trying to connect a + and - button to R, G and B to increase and decrease each one separately however when I copy my code into to the mousePressed section, it does not recognise [i] in terms of pixels. Can someone please help. I am new to processing and suck at it!
