Number counter

Hi,
We have a automatic campaign running for a Kids club. Every child, gets an cupon code on their birthday. We would like to add an unique number on theese mails. We have tried to make a very simple javascript with a counter and a random number generator, but we can get the scripts up running.

Can we somehow, make it possible to add a number in all mails just as a counter or af random number?
