You would have to debug it. It may have SQL injection code preventing complex values like that to be passed in directly. This is not part of our testing, so it isn't really directly supported in this way. You may need to do some hand edits to get something like that working properly. Write the resulting SQL statement to the page and see if it writes what you would expect. It may work I just haven't tried that technique which is why I recommended creating a view so the concatinated fields appeared as a single column.
