That now works perfectly.. many thanks.

Why will it not accept a wildcard in count such as count( t1.*)
instead it needs a collum name.. not important.. just unexpected:)


I do have MySQL by Paul DuBois and its looking a bit ragged now I
have used it so much.. I just can't seem to get my head around the
join ..erk :( More reading and more testing I guess.

Many many thanks for your answer Stefan . Much appreciated.
