Steve, also read this...

17.2.10 A/D CONVERSION PROCEDURE

This is an example procedure for using the ADC toperform an Analog-to-Digital conversion:1. Configure Port:• Disable pin output driver (See TRIS register)• Configure pin as analog2. Configure the ADC module:• Select ADC conversion clock• Configure voltage reference• Select ADC input channel• Select result format• Select acquisition delay• Turn on ADC module3. Configure ADC interrupt (optional):• Clear ADC interrupt flag• Enable ADC interrupt• Enable peripheral interrupt• Enable global interrupt

(1)

4. Wait the required acquisition time

(2).5. Start conversion by setting the GO/DONE bit.6. Wait for ADC conversion to complete by one ofthe following:• Polling the GO/DONE bit• Waiting for the ADC interrupt (interruptsenabled)7. Read ADC Result8. Clear the ADC interrupt flag (required if interruptis enabled).

Steve, I also don't see where you are setting the A/D reference voltage source...
