that is because the error is occuring on line 267 of the combined file in IE. after internet explorer combines the include file into the code.
this is the error just like i put previous:

I will attach the source code right out of IE8 in a word file, then you can see what i am talking about. I have put (Line 267) in the text at that point so you can see which one it is.
