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 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?
