<h3>Database Error</h3>
Sorry, a database error has occurred.
<p>
You should set up a database of your choice and then modify the variables DBProviderAssembly, DBConnectionType and
DBConnectionString in <tt>xsp.exe.config</tt> (or <tt>mod-mono-server.exe.config</tt> if running the tests under Apache/mod_mono)
file to fit your needs.
<p>
The database should have a table called customers created with the following command (or similar):
<pre>
CREATE TABLE "test" (
"person" character varying(256) NOT NULL,
"email" character varying(256) NOT NULL
);
</pre>
</span>
<form id="theForm" runat="server">

<asp:TextBox id="PersonFilter" Text="" TextMode="singleLine" runat="server" maxlength="40" />
<p>
