Hi,
The problem is this, i have a combo box that as a result of selecting something it opens a form where i select a price by checking a check box. once a check box has been selected i can close the form and finish creating the invoice. however when i change a different combo box first i get a error saying there was an invalid use of null. all I want to do is put an if statement so that when the wrong combo box is selected/modified first a prompt pops up telling the user to start at the proper combo box. any suggestions?
