i WORK WHERE WE DO CAR RENTALS AND THE PROBLEM IS THAT i WANT THE KILOMETERES
TO BE COUNTED.

i HAVE THE KM WHEN THE CLIENT LEAVED ( A ) WHEN HE COMES BACK ( B) BUT i CAN
FIGURE OUT HOW TO GET (C) TO AUTOMATICALLY CALCULATE THE KM DRIVEN. I HAVE
TRIED TO READ THE FORUMS BUT MAYBE MY LITTLE MIND CANÈT GRASP IT.
ANY HELP?
THANKS IN ADVANCE....
