You could have Access open up the form with the report title chooser combo-box when it opens up. Use the combobox to set the Report title by using the Set Value (VBA or Macro), if you use the =[forms]![yourformname]![comboboxname] method, then the combobox will have to be there EVERY time a user opens the report.
Then on close button of the form, use a macro that does this
- Ask if user want to set Report title to [Report Title], which should already be stored in the report title label
- If choose YES, then close form, and then delete form AND table that is storing Report Titles that the Combobox is looking up (Or keep it in case you need to use it again for some reason).
- If choose NO, bring back user to the form to choose again.
A macro might not have the options you need so VBA might be required.
Hope this helps!
