When attempting to add a station equation, the follow message is received: "Duplicate ahead station"


When entering the ahead station, you must specify a name for the station equation. An alpha character must be included in the ahead station to differentiate the ahead station from the back station. For example, suppose you want to define station 12+00 back to be 13+00 ahead, you would enter the back station as 12+00 and the ahead station as a13+00.  Each station equation must have a unique alpha character.
