So simple, so good...Tested, it works great. I can even use
...iif(orders.fromloc > orders.toloc, locs1.name ) as Startname....
Thanks for your great help

>>Hey Boris
>>Thanks for the fast answer. In fact, i simplified the query just to ease understanding. I cannot round them, those are id's of locations. In the real select, it looks like
>>select .... locs1.Name as Origin, locs2.Name as Dest .... from orders join locations locs1 on orders.FromLoc=Locations.LocationID ;
>>join locations locs2 on orders.ToLoc=Locations.LocationID .....

Why do programs stop working correctly as soon as you leave the Fox?
