I am no pro in Excel. Please, I need to figure out how to create an
inventory speadsheet that will update the current inventory when saved.

A1) product B1) amt sold C1) price per unit D1) original inventory E1) D1-B1

I'de like to save the updated E1 inventory after each order, clear B1 for
the next order and have E1 always reflect the current stock.

If I save and clear B1, E1 reverts back to D1 quantity.

Thanks for any help.
