James, This almost crossed in the system. I was in the process of=20 answering the email just prior to this one. The crystal just wasn't=20 oscillating. The MicroChip descriptions can be confusing at times. I=20 also just learned that the faster a crystal runs the more drive that it=20 needs. And Joe reminded me that you should have a bypass cap hooked up=20 to the PIC. I hadn't done this. Thanks, rich!
