Can someone explain why I get an error from:
SELECT Travauth.travid, Travauth.actid, Travauth.empid, ;
       Travauth.tanum, Travauth.dcn, Travauth.amount, ;
       Travauth.bgndate, Travauth.enddate, Travauth.destid, ;
       Accounts.account, Accounts.allotment, Destination.city, ;
       Destination.state ;
 FROM travel!TravAuth ;
      LEFT OUTER JOIN travel!Destination ;
           LEFT OUTER JOIN travel!Accounts ;
           ON Travauth.actid = Accounts.actid;
      ON Travauth.destid = Destination.destkey;
 ORDER BY Travauth.empid, Travauth.tanum
The error is: SQL: Column 'ACTID' is not found

If I switch the order of the JOIN and ON statements, I get the error:

SQL: Column 'DESTID' is not found

If I have the source tables open before I issue the command, it works. All fields exist, and I can create the view in View Designer. Once I save and exit the designer, I can not edit it in View Designer because I get the error.

Once the view is created, the source tables have to be open before I open the view.

TIA.
