HI, I am trying to set up a form when a user can upload three images at once: one for a logo, one for a city map and one for a country map. These images are used by a ZClass (Base classes: ZCatalog Aware, Object Manager) to display a hotel web page, with info about this hotel. Authorised users are supposed to create this hotel instance. I created a Hotel_add_form: <HTML> <BODY> <p><h2>Here you can upload hotel logo and maps into the hotel file.</h2></p> <form action="map_add" method="post" enctype="multipart/form-data"> <p><b>Logo</b></p> <input type="hidden" name="logo_id" value="logo26"> <p>Title: <input type="text" name="logo_title"> </p> <p>File: <input type="file" name="file"></p><br> <p><b>City map</b></p> <input type="hidden" name="citymap_id" value="map26"> <p>Title: <input type="text" name="citymap_title"> </p> <p>File: <input type="file" name="file"></p><br> <input type="submit"> </form> </BODY> </HTML> and a method map_add <dtml-call expr="manage_addImage( id=logo_id, file=file, title=logo_title)"> <dtml-call expr="manage_addImage( id=citymap_id, file=file, title=citymap_title)"> <p>Thanks for your photo submission.</p> Unfortunately when I try to use it I get the following error: Zope Error Zope has encountered an error while publishing this resource.
