Q:

Javascript split working incorrectly in IE

I have one page checkout. My OPC works fine with other browsers but I get a fatal error with IE. IE's Javascript console says Object doesn't support this property or method.. The method in question is var items = field_name.split(reg) from the file: order-address.tpl.
I have no idea what is causing the problem. Because of this error, I cannot login properly from one page checkout when using IE. It seems that there are a lot of people with the same problem. What's the issue?
This error is present in 1.4.9, 1.4.10, and 1.5.3. 

A:

SOLVED. It turns out the issue is not with coding but with settings of IE.
All I had to do was reset IE from Tools => internet options => advanced => reset (including personal settings)
That did it for me. Thank you altafhussain for trying to help me out.
