I'm relatively new to using Microsoft Access so please bare with me. I have a table with which contains "Items", "Price" and "Quantity". Now I was wondering if it is possible to set up a couple of forms, one for customer purchases where I can select an item out of a combo box and enter in the number of items purchased and it then subtracts this amount from the amount in the table. Similarly I also want a form where i can select an item and enter in the quantity of stock I purchase to replenish stock and this then adds to the quantity in the table. Any ideas would be appreciated thanks.
