>Thanks very much. I wonder if it's the positioning I'm doing wrong. A statement like:

>inner join table2 b on b.somefield=a.somefield

then the error goes away. ????

JOIN is used to specify the realtionship between the files, WHERE is used to specify which records you want. So JOIN is like SET RELATION, WHERE is like SET FILTER.
