I have a form that has a tab control on it that has four tabs. One of the tabs has a subform on it and one field. I would like for the following to occur when the user clicks on the 4th tab.
If the one field on the tab is not null then the subform should not be visible else the subform should be visible. This works on non-tabed forms using the on current but I cant seem to get this to work on a form with tab ctl using the on tab click.
