Thanks for reading this all!

Have a custom add-in to drive certain statistics in a report. The add in is
checked, after running the report several times, the add in driven portion of
it does not produce the proper output. Looking via the drop down menu, the
custom add in box is checked. The report works again if I go through the
menu steps of adding the add in back in. Sheet is protected after each run.

Would anybody have any ideas why the add-in doesn't work, but is still
checked OR any other suggestion solutions. Thanks kindly.
