          Caption ="Click me - Back to page 1"
      Click= thisform.pageframe1.activepage=1
  3. Set the following properties and events of the combo box: 
          RowSource = 1,2,3,4,5

  4. Run the form.

    Click Page two of the page frame. Next, click the drop-down combo box and select any number. Note that the GotFocus event fires before the Valid event.
