I really have no clue on javascript and this is someone elses code, but does anyone know why it causes the above error in internet explorer?

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.
