Fejl i insert into

Ey jeg har igen probs med insert into sætning når jeg reponse.write strSQL'er skriver den INSERT INTO News (Date, Header, Text, PictureName) values ('18th Mar.', 'Testing', 'Testing', '001.jpg');
og insert into tingen ser såen her ud:
strSQL = "INSERT INTO News (Date, Header, Text, PictureName) values ("
strSQL = strSQL & "'" & Dato & "', "
strSQL = strSQL & "'" & request.form("header") & "', "
strSQL = strSQL & "'" & request.form("text") & "', "
strSQL = strSQL & "'" & request.form("picture") & "');"
Conn.Execute(strSQL)
