Try to avoid multiple inner statements. You can create a query in two steps or use something like:
SELECT Tproduct.fpname, Ttooltype.fttype, Tvendor.fvname;
FROM dbtwiz!tproduct, dbtwiz!ttooltype, dbtwiz!tvendor, dbtwiz!ttool ;
where Tvendor.fvnum = Ttool.fvnum and;
Ttooltype.ftnum = Ttool.ftnum and;
Tproduct.fpnum = Ttool.fpnum


>When I try to create a query in the designer I get an error when I try to save the query.

>The query runs fine, but it wont let me save it:
>
>"query parse error-try rebuilding in query wizard or by using view designer join tab"
>
>It always happen when I add the fourth table.
