I have built a dbase that house information for parts (cost, manuf, part#, etc.) we would like to have this dbase track inventory as well. Rather than just having a QtyOnHand field that a user can adjust, we would like to have them go through a form that asks "are you adding inventory" or "are you depleting inventory" and then enter the # of parts added or depleted. That entry would then adjust the QtyOnHand. But how? How can I accomplish this? I have no doubt that it is a simple answer, it's just not coming to me. Thanks!
