Thanks Jason.
I've done that and it's not working but I think it's because my data has a comma separated list and so does the search string.
To clarify, my data has something like this in a single field:
UK, USA, FR, ES, IT
The search string may have something like this:
UK, FR, DE
The record needs to be selected because there is at least one match (UK and FR will match in this case).
How can I do this?
Cheers
Jon
