Hey Jshoplist, If I'm reading your posts correctly the total quantity should be 2 not 4? If so the reason you're having this problem is that you made the initial quantity 2 and then added 2 more with the expense/purchase. If you are going to enter the 2 through the purchase then your initial quantity needs to be set at 0. If you edit the inventory item look under "Quantity on Hand" there should be a clickable "starting value" click that and adjust your starting quantity to 0. Then every time you purchase that item and expense it it will add more inventory.

Hope that helps.
