Wilfried - thanks for your help on my php post - i was being stupid, works fine now.
I am having problems with the Calculate method.
I am adding two waypoints and using the calculate method. The two waypoints (Lat, Long btw - in case that makes a difference) go in fine but the Calculate method ends in an error:
'Error Member not found. '
I can click the "Get Directions" button in the open mappoint and it works fine.
Is there anything i should be looking out for?
