I found the issue. Apparently IE doesn't set the name of a form field  
when using createElement. I found this solution in this thread:

View the 3rd comment (from A1ien51). He provides a link that has a  
workaround for it:

View the source and see how he deals with it. I plugged it into my  
code and it works perfectly. Hope this helps someone else having the  
same problem...

Thanks,
