Omiting duplicates in a set

[gmd]

I am a beginner so this may be very simple but I am having problems. I have a found set and I want to omit lines that have a single field the same. When I use Constrain Found Set to omit a search for ! for the field, it removes every line in the found set if it has a duplicate anywhere in the database.

I am a beginner with FM but have coded in many languages for years. I have tried writing scripts to loop through the data and compare each field, omitting duplicates, but something is definately wrong because my script never ends. I memory and cpu are not eaten so I wonder if something is simply wrong rather than going into an infinate loop...

Thanks for any advice!

Nevermind, I wasn't running into a loop problem, I just didn't have the script terminating
