Clear the form and only fill in the 'country' field. For example, type in 'USA'. There should be over 500 entries for that search. If it still does not work, it may be the browser you are using. Be sure you are using a Netscape 2.0 or compatible browser.
Older browsers have a problem with the radio buttons found on many forms.
Please tell us what browser and version you are using. When I go to edit my entry, the search engine can't find it. Be sure that you are providing the first and last name exactly as it appears in the directory. To double check, search the directory for your entry. The goal of the directory is to help people find each other.
