Is this this script ok ? (it works), but I'm Looking for some advice on the best way to write it.

thanks for all your help.

Yeh, It looks fine, no where you can really slim it down that I can see.

Would this not be best done using calculations rather than a script?

The user enters a whole bunch of data and THEN the auto-enter fields trigger? Not sure how that could work but...

However am I scratching my head here, why copy in the first place??? This looks like a many to many relation.... which would require the ID's of each the records into the newly created record only!!!
