Hi to all and thanks for the support,

I have a list box with family names. When the user clicks
on a name another form opens, FamilyMembers, showing all
the family members. This works fine.

Now I would like to add a button next to the list box with
the following behaviour: If there is even one record in
the list box the button will be inactive. If there are no
records in the list box the button becomes active and
opens the FamilyMembers form to a new record. How can I
count the records in the listbox?

Any help will be greatly appreciated
.
