Basically, this is a case of basic programming memory loss. In the code below, I simply need to know how I can use the address that is already in the map (the one you define in the map settings and/or the one currently displayed on the map) instead of the information from the inputSource field. Something to the effect of var source Address = get.geocode("Address").val();
var sourceAddress = Appery("inputSource").val();
var destinationAddress = Appery("inputDestination").val();
var map = Appery("directionsMap").gmap;
displayDirections(sourceAddress, destinationAddress, map);
