The Meeting Number field was increased from 3 to 4 characters in SAMS 3.01.18. If you did not click on "Verify on every print" when you created a custom report, then please do the following:
1. Open the report that isn't working
2. Click on Verify on Every print
3. Click on Verify Database
4. It may display a message about files that have changed. Click OK every time that message occurs.
5. Go to the Selection Expert. If you are using a specific Meeting Number in your selection, make sure it is 4 characters long, i.e. 0109.
