I am receiving this error when I click the explanation point after I write the query.  I am brand new to this type of work, so if my question is misworded or I am just being stupid, be kind.  But the list I am trying to work with resides here:

http://spstestsrv/Lists/Test SQL/AllItems.aspx

so this is the code that I entered,

<?xml version="1.0" encoding="utf-8"?>
<root>
    <list title="Test SQL" relativeSiteUrl="/lists/" tableName="results" useDisplayName="true">
    <fields></fields>
    <query></query>
    </list>
</root>

I receive an HTTP 404 error.  Any ideas?

Hi,
Try with only a slash "/" as the relativeSiteUrl attribute.
The datasource connection string should be "server=http://spstestsrv"

Are you using a WSS install only or did you create your list on the portal?
Let me know if you need some more help...
Regards,
