Duplicate Subform Found

I am getting the following error:HTTP Web Server: Application Exception - Duplicate Subform found. A given subform cannot be used on the same form more than one time. [/Apps01/Forums/forum_test.nsf/ViewForSearch?SearchView&Query=Field%20CategoryID%20CONTAINS%20%2223%22%20AND%20Field%20Subject%20CONTAINS%20%20%22%22test1%22&SearchOrder=4&Start=1&Count=25&SearchMax=5000&cat=23]

The search form and the form being searched have no subforms.

They did originally - but in trying to debug the problem - I have removed everything and am still getting the error.

There are no embedded views - no formulas (formulae?) to show computed subforms.

This is purely a web application.

There are standard shared fields (dbname, query_string, etc.), a computed value that is a dblookup + some common web fields - $$HTMLHead, $$Return. The search is done using formula language which is very, very similar to a search in a different database (that works).

Subject: How about $$SearchTemplateDefault?

Subject: That was it - THANK YOU!
