Well, i'm sorry if the information it's no enough but... i think that the problem it's more general. The reported error is visible whatever page i could try to access with my browser.
An exemple... http://draco.salleurl.edu:15000/index.tcl
I tried to make a default.tcl page that don't uses any ArsDigita function with the next code inside:
set page_content "
<html>
<body>
<table>
<tr><td>Your email address:</td></tr>
</table>
</body>
</html>
"
doc_return 200 text/html $page_content
I just use the "doc_return"
Here there's no variable named "query" and the problem is the same.
Thanks again!
