When running District Attendance Letters for the first time in the school year, users may encounter a "No Letters Found" error if the "Include Prior Dates" option is selected. This occurs because no prior letters exist yet for the current year.

To improve user experience and reduce confusion, please consider enhancing the message associated with this option to:

Inform users that no prior dates are available when running letters for the first time.
Recommend that users uncheck the option to proceed successfully.
This enhancement would help clarify the behavior and guide users toward the correct setup, especially at the beginning of the school year.
