We have a form that records the number of wafers per container using text boxes. There are 34 of these text boxes. At the bottom of the form is a text box for the total number of wafers from the 34 text boxes. As the user enters in the number of wafers per container, we need the total number of wafers text box to update with the total quantity. Will I need to have an event for every ‘per container’ text box to update the ‘total quantity’ text box? A better way?
