[Zope] problem uploading pdf file via localfs

Hi everybody, I hope you are the right people to address my question. If not, please tell me who might help me with the following question: I am trying to upload a pdf file via a localfs object. Unfortunatelly I am getting a blank page to see within ms-ie. This is the code I am using: <dtml-var standard_html_header> <a href="pdffiles/deutschA.pdf" type="application/pdf"> upload </a><br> <dtml-var standard_html_footer> Thanks in advance, Metin Deniz
