GradeSchool merge error

[Joe Gordon]

For letter merge for a school form, when I include GradeSchool as a Patient Field, I get this error when I Preview:
Unknown column 'patient.GradeSchool' in 'field list'.
I then have to Quit and OD program closes.

Figured it out with support:
GradeSchool is no longer a valid field. It has been replaced by SiteDescription. They may delete GradeSchool so no errors occur.
