      OK, I see the problem: the column
"EndReading"."Odometer" - "Fuel"."Odometer". In the Criterion row, "=>0" 
(without the quotes) was used. The order should have been reversed. 
Change this to >= 0 instead.
      In working with this a little, I noticed another "error". To 
correct it, make another change:
The cells of the first Odometer column should have Odometer, Begin, 
Fuel, (Blank), and a checked box in this order from top to bottom. The 
cells of the second Odometer column should have Odometer, End, 
EndingReading, (Blank), and a checked box. These two Odometer fields had 
been assigned to the wrong thing in the Table row.
      Thanks for helping me catch my errors.
