Filemaker 11 Unique Field Content Error 504

[JH Howland]

I have a database field set with a validation of "Unique value".

I am trying to revise a script that loops thru all the records and updates the value in the field.

Currently, my script loop stalls when the value written in a record is not unique.  I want to bypass writing the updated value if not unique, but I can't find a way past the Filemaker error code 504.  All I can do is manually "Revert" to the original field value.

Suggestions?

Why can't you capture the error and have the script do the reverting?
