I have some simple VB coding to handle some arithmetic. When the user click an option, the VB either adds or subtracts the cost of the item (depending on true or false) to the total cost field. I also subtract from this the credit balance to arrive at Amount Due, which is put in another field. The Total Cost field updates immediately, while the Amount Due doesn't reflect the changes until a mouse over of that field!!! I change both the Total Cost and the Amount Due in the same subroutine. What do I need to do to have the Amount Due field update at the same time as the Total Cost?
