Comment form problems

I am having some problems in the comment form of my individual archives.

After entering a comment, the form correctly sets the mtcmtauth, mtcmtmail and mtcmthome cookies.

But if I view the page later, the contents of these cookies are not loaded into their respective fields (I’ve tried it with Moz and IE6). My browser tells me that document.comments_form.email is zero or not an object. Of course I checked my template, but I cannot find anything strange.

The <form> element has id=“comments_form”, and the field is also nicely called email.

I don’t know where to look further anymore. Can somebody have a look at this page, and help me with the solution?
