I am trying to create a SELECT statement consisting of multiple tables. The tables are parent=Nameplat, child1=Dga, and child2=Visual. All three tables have the fields Custid and Upsino in common. When I join just the Nameplat and Dga based on Custid+Upsino, it works perfectly and very speedy. However when I try to add the Visual table I get way too many records, over 4000 versus 462 in my test query. I plan on using this SELECT statement for the record source of my report, and I want to add a third table to it. This third table is a Parent over the Nameplat called CUST. Here's the SELECT statement I'm trying to make work:

SELECT dga.upsino, dga.puldat, dga.hydrogen, ;
nameplat.serial_no, nameplat.manufactur, nameplat.upsino AS "upsinoname", ;
visual.optemp, visual.upsino AS "upsinovisual", visual.datinp ;
 FROM nameplat INNER JOIN dga ON nameplat.custid+nameplat.upsino=dga.custid+dga.upsino ;
 INNER JOIN visual ON dga.custid+dga.upsino=visual.custid+visual.upsino ;
   INTO CURSOR rdga ;
  WHERE dga.custid=gcCustid ;
ORDER BY dga.upsino ASC, dga.puldat DESC, visual.datinp DESC
REPORT FORM dga2 PREVIEW

What am I doing wrong here? I have been trying this one for quite a while now. Will I be able to add Cust to this SELECT statement? Any help much appreciated.

Thanks
