Creating web form does anyone know how to add a unique number to each form submitted

[matthewr12052850]

We are creating a web form that is a sign out sheet for employees. We would like to add a unique number to each sheat.  Somthing like sheat 1 , then sheat 2.  So each time one is filled out the numbers go up and up.  Any help would be greatly appreciated.

This is only possible if there's only one copy of the file in existence, or you apply this number in a centralized location, or use a complex web-based script to assign each form with a number. I would recommend using something like, such as a time-stamp or a random number, instead.
