no browse button for file upload field in permalink form

The permalink page ( http://creator.zoho.com/drlith/page/12/) for my form does not show a "browse" button for the file upload form. The field does appear to successfully upload a file if you are able to input the exact name/location on the local drive. It also gives you a "the page you are viewing contains POSTDATA" dialog upon success.
