I came across a class for integrating google maps into my website at www.TrackTheSpraying.com. Now to explain the concept here basically the end user submits a location (Full Address or City,State) than it pins the location on the map.
After a few submissions i get an error saying no address found for location.
can someone please help me and look at the code here and tell me what causes this....
I have been stumped for quite a while now.
Thank you !
