Hi and welcome aboard!
Rule #1: post your code here and we will help you to spot the problem... unless you may end up with comments like "My crystal is broken..." and plah plah plah :D
Rule #2: Have you checked with a voltmeter that the desired signal is present on the legs of the PIC and that the level is less than VDD.
Could find a edit button.

yes the signal is present on the leg of the pic but i just get a 3 diget number that keeps changeing and doesnt respond when i turn on my potmeter
I think you will have better luck on the Proton forum.

When you post there you will want to describe how you have the hardware setup along with the code.
