Making global values available to all

[André]

I have a table of several thousand records and a global timestamp  
field. A user-activated script sets the timestamp field when it runs.  
However, other users can't see the value in the timestamp field,  
because globals are user specific, and thus can't tell when the  
script was last run. I'm stuck in a rut. Is there a way around this  
or another approach altogether? Can I have a timestamp field that  
applies to all records in a table and displays the same value to all  
users when set by any one user?

The file is hosted on FMS 10 and clients are FMP 10, all on Macs, OS  
X 10.4-10.6.

Thanks for any suggestions.
