I tested with some bogus data here and there doesn't seem to be a problem. The difference is I'm using userCoorPath for the polyline and userCoor to set the markers. I'm repeating the information, but they are being used differently.
One is an array of LatLngs, the other an array of string and two floats.
You are not setting the marker icon property.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
