    I think Melanie is on to something, check +5V supply. If jumper JU2 (close to the ISCP connector in the Board Schematics) is missing things will not start. If it is missing programming will work but when you remove the Epic, +5V will not go to the PIC. Guess it is time to bring out the old voltmeter.

    I want to thank you both! The program was correct as Melanie stated and thanks sinoteq for looking at the schematic. Since I didn't want to use the boards ICSP for programming the pic I didn't even read that part of the document or look at that part of the schematic. All that was needed was two little jumpers! one of them being JU2 and the other a jumper for a diode. Thanks again!
