Is it possible to increment it on use of the submit button. If you are submitting from a single computer could you save and write to a .txt file that would store the current number and could be done automatically from within the script and gives you the ability to edit the .txt if needed.
I would like to do something similar, good luck.
This form needs to be accessed from Multiple computers on the network. So does that mean this can not get done?? I appears not doable at this time...
