I can't do that.  The whole "app" is just two tabs on
one I have some command buttons and the other sheet has
a subform that I assign the records source to at run
time.  I don't want the user to be able to select the
"Date" tab with its unbound and blank subform until
after they have clicked on one of the command buttons
and run the code which builds a table and then assigns
it to the subform.  At that point, I'd like to change
focus to the Data tab.

I distinctly remember doing something very similar to
this in VB6 a year or so ago and it was not the brain
twister this one is proving to be!  Heck each page has
an Enable property but I can't figure out how to
reference it.
