Couple of Things:
1. There is no Boolean Variables right out of the box for MPLAB. You can get them by assigning your variables as int and then have:
#define TRUE 1
#define FALSE 0
at the top of your code
2. Try and use indentation. It will make debugging your code a lot easier
3. I have noticed a lot that MPLAB doesn't like when you don't use {} on single line For/If/While statements. That is why I put those in.
4. == is for conditional statements. IF / While statements
= is for assignment statements. There were couple of places where those were messed up
