in reply to IE vs. Firefox : Can't use an undefined value as a HASH reference error
I'd take a guess that Firefox is setting the content-type of the form to 'multipart/form-data' when it sees the upload field whereas IE is not - you should put the enctype attribute of the form element ie.:
<form method="post" action="whatever" enctype="multipart/form-data" +>
/J\
