I am modifying the Assets database (template in Access 2007 beta). I have added Qty as a field in the Assets table and all related forms/reports. Currently, the Asset List form allows me to pull up the an item and edit the Qty field directly (ie, I could change QTY from 10 to 20). However, I would like to build a Add Qty form which would allow me to put a number in the QTY field which would add that number to the current value of the QTY field (ie I have 10 apples, I open the Add Qty form and in the the QTY field of Apples product I would type in 15 (now my total QTY is 25 apples). Likewise I would like to have a Remove Qty form to remove Qty in a similiar fashion.
