Thank you Paul. I am missing "Microsoft Calendar Control 11.0". Here's how the problem arose:

I previously had MS Word templates that drew data from MS Access databases that were created in an older version of MS Office. The VBA instruction referenced an "mdb" database. When I created a new template and new MS Access database it didn't work. Another member of this forum advised me to change the VBA instruction to reference an "accdb" database, and to delete the reference to Microsoft DAO 3.6 Object Library and replace it with a reference to Microsoft Office 14.0 Access Database Engine Object Library. I did that, and I am now able to draw data from the new database. However, the MS Word form that I use to do that includes a calendar control. That calendar control no longer works.

I have looked through the list of objects available to reference. I do not see Microsoft Calendar Control 11.0. I have tried deleting the calendar from the form, saving it, then re-opening it and re-inserting the calendar. It still does not work. Is there some place I can find Microsoft Calendar Control 11.0 and insert the reference manually?
