When an agent completes an enrollment, I need them to be able to click a button, have this button generate a random number (into a form box), from a pre-defined list of numbers, and that number cannot be used again. Ever. I also need the button to gray out after receing ONE number. A cookie will need to be setup in case they hit F5 and refresh. I need the charachters to go as high as 6 digits, ATLEAST. The list it pulls from, must be pre-defined, we have to be able to acknowledge the number has been used, and cannot be used again.
Example (List) :
This would be a list I create, and it has to follow that list.
