Hello John and Neil.
Neil: it's hard to track down a fault you can't see.
DC: Yes you are right. And a long time passed since I made the programm.
Haved you by any chance made some change on the data in the form "Cross issue by date (Maintenance)" or used the option "Import from an Excel file"?
Couldn't find, yet, the cause of the problem.
Meanwhile I've put in my site a EiM_Index ziped file with new data base file.
Please download it, try it, and let me know what happens.
Thanks in advance
