      results = ShowTabbedForm('Title for the form',

+Each of the tabs of the form is in fact a form.  The same steps are taken to create the form as before.  A `FlexForm` is created, then rows are filled with Elements, and finally the form is shown.  When calling `ShowTabbedForm`, each form is passed in as a tuple.  The tuple has  the format:  `(the form, the rows, a string shown on the tab)`
+
+Results are returned as a list of lists.  For each form you'll get a list that's in the same format as a normal form. A single tab's values would be:
+
+    (button, (values))
+
+Recall that values is a list as well.  Multiple tabs in the form would return like this:
+
+    ((button1, (values1)), (button2, (values2))
