I had a problem where attachments were being displayed at the bottom of the web page. I wanted to hide the attachment until the user had logged in. This is a quick way of hiding these attachments.
Stick on the last line of the form:
<noscript>
and make it pass thru HTML.
To make it dependent on whether the user is logged in or not, make a computed text element with the code :
@if(@username="Anonymous";
"<noscript>";
"<u>Attachments</u>")
