I believe that the CMCON = 7 was key. I had tried all the other settings backward and forward trying to get it working before posting to this forum (Adcon0, Adcon1, Adcon2) but I had forgot about CMCON.

Once it was working - most of the resistors I tested on the Photocell (breadboard) came back with results. But once I started looking into the resistance values on my prototype, I found that an incorrect connection was made under a capacitor (SMT) which gave me false readings. I rewired and changed the settings - it then started working.

So what this forum gave me was several clues to finding solutions two different problems. I really appreciate all the time and effort you guys put in to helping everyone here online.

You guys make using PICs and Picbasic Pro possible!

Thanks again!
