Thanks for your response Scampy!
I was just wanting to use simple code to get the ADC to work. With the help of Richard's code (from the MELABS forum) I was able to get the ADC to work. Thanks to your help I re-looked at the rest of my code, and I found the issue. I had set PortA.2 to an output later on (by mistake!).

So, all is working PERFECTLY now!!!!

Thanks again!!
