I have a relationship of files that are related and clicking in between relationships that exist is fine. However if the relationship doesnt exist how can I flag this up and ask the user if they want to create a new related record or add this number to an existing one?

Thanks

Simon

Yes. On another list we discussed this. Jimmy Jones of FileMaker Inc. stated that IsEmpty is optimized for this use. IsValid, although it appears to work fine, was never intended to be used for this purpose.

I've always used Count ( relationship::remotekey ) though I can see how it may be slow if there are a lot of related records.

I used to use relationship::constant. It would be much faster than Count, but apparently IsEmpty is allegedly even faster.
