changed things around a little. it now displays the current stock level and then allows you to go and add to it. so instead of having to go and count the number of that item you have each time you get a "truck" all you need to do is input that you got 3 of that item in today. so if you had 5 and got three, you'll end up having to only input 3 instead of 8 like it was on the old system. screen shot is included.
