Use:

 

select trxtal.groupno as groupn,artwork.artworkno as artworkno,count(trxtal.groupno) as grp from (trxtal, mstcus) LEFT JOIN artwork ON (trxtal.groupno=artwork.groupno and trxtal.classcode=artwork.classcode) where trxtal.groupno=mstcus.groupno group by mstcus.groupno having sum(artwork.artworkno)>0

 

But really, don't use commas to join tables... it's very bad form.
