I ended up adding some javascript to disable the button once clicked, and then putting in code in the php to prevent duplicates. It seemed to do the trick. I can send over some sample code if you need. For the javascript I just made the submit button hit a function, disable the button, then submit the form. -- -Dan Joseph "Build a man a fire, and he will be warm for the rest of the day.
