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.

SELECT Tproduct.fpname, Ttooltype.fttype, Tvendor.fvname;
FROM dbtwiz!tproduct INNER JOIN dbtwiz!ttool;
INNER JOIN dbtwiz!ttooltype;
INNER JOIN dbtwiz!tvendor ;
ON Tvendor.fvnum = Ttool.fvnum ;
ON Ttooltype.ftnum = Ttool.ftnum ;
ON Tproduct.fpnum = Ttool.fpnum
