I have a form where you can order products from and then you can print out the Purchase Order report directly from the Order Product form. There is a subform within this form where you enter in the quantity etc. I would like to be able to number each product I order 1, 2, 3, and then have it pull it up on the PO as the Line Item #. But I would like it to reset each time I order something new, so a runningsum doesn't work. Do you have any idea on how to do this I am not sure if I do it on the form or the report. HELP I AM IN NEED!!!

Here is an article for the Subform:
