I designed a large and involved Dialog, that I found that everytime I made a change I left the UserForm pointing to the wrong tab. My customer always wanted the tabs to open in logical order.
Value Ø (zero) forces the first tab to be dispalyed on open.
usrCostB.MultiPage1.Value = 0 'Main
Now I want to figure out how to force a recalc when I go to the next tab.
