Hello Everybody, I'm looking at somehow having a cell with a total number based off two other cells. One would be an amount added and the other cell amount subtracted. However these two cell entries need to be ignored once entered. Maybe a simple example be wanting to know the total number of boxes in stock where our MRD target is 10 boxes. So if production makes 2 boxes they enter 2 boxes into a cell our current total is 2 boxes, if production make another 3 boxes and enter into the same cell we have a total now of 5 boxes goal to get to our MRD target of 10 boxes. In another cell we would be doing the same but its an entry of boxes going out when these are sent off-site by the store person.
