Thanks Bob, but this is exactly what I'm doing. The only difference is that I'm using 2100 instead of 9999...I solved the problem using CTOD("31/12/2100") instead of {^2100-12-31}. Thanks for the manual, but I could not download it from my ISP. I'm waiting for Kevin's message with another copy.

Regards,
