Hi, Thanks for the reply.
I'am trying to mix Gdirections with Gmarkers... I explain well... I'am
taking this example:
http://code.google.com/intl/pt/apis/maps/documentation/examples/directions-advanced.html
But I need to initialize the map with a Marker without a Direction
Instructions, the Map when initialized will show only one Marker(A),
then I need to get the Directions to the Marker(A) from a given
Direction that I input in the TextBox. This is possible?
My code:
