'__e3_' Is Null Or Not An Object - Google Maps

Message: '_e3' is null or not an object Line: 19 Char: 1068 Code: 0 URI: http://maps.gstatic.com/intl/en_us/mapfiles/api-3/6/6/main.js I really have no clue on javascript and this

Solution 1:

If you open IE's developer tools, change to the script tag, and start debugging, then when the page refreshes and the error occurs, the developer tools will show a call stack headed by your call to add a listener to the drag event of a marker, and the __e3_ being referenced is a property of the marker, but you have not created the marker.

Move the addListener(marker ... call to within the initialize() function, after you've created the marker.
