I'm working with the sample located at: https://github.com/Esri/basic-viewer-template which pulls maps from ArcGIS.com using an ID number for the map. I need to convert it to utilize a KML file in the same directory instead.
What I have so far is located at: www3.bryguy.org/Map Viewer
Most of my experience is with C++ and Visual Basic Script but I'm pretty good at deciphering any coding language so even if you're only able to provide basic assistance that would be helpful.
