Autonumbering certificate in Office 97

What is the best way to create an autonumbering field in Office 97. I have access, excel, and word, and I need to create a certificate to print that will automatically increment to the next number in the sequence. We have to print out like 50 of them, so it is too much a hassle to do it by hand.

What is the best program to use? And how do I do it once in said program. And how can I start with a specific number? Not necessarily ‘1’.

Thanks
