linking values to auto calculate

[smiller]

I have parts that go into and out of inventory. Each time a part is removed or returned, the user inputs the number into the computer. I was wondering how I could link the numbers so that as parts were removed or added, the total number in inventory and the total number on the floor automatically changed. Thanks so much.

Do a search in these forums for inventory or stock control. Calculating balance on hand is a common topic.
