Workaround only appeard to work once. Has reverted back to the old script even though it's been deleted.
Thank you for your posts.
I am unable to replicate the problem. I created a database file in Mac OS X 10.6.8 with the script to set a field for Get (CurrentDate) + 28. When I take it over to Mac OS X Lion, I am able to change the script so it sets the field to Get (CurrentDate) + 56, and it works properly.
In case the script is damaged, duplicating the script could also duplicate the damage. If you recreate the script from scratch, do you get the same problem?
Are you running any plug-ins? If so, try disabling them and try again.
Any other information you can provide about your computing environment may be helpful.
