web assessment

Hi ShadiRegarding the accessibility status of the following web site http://www.w3.org/WAI/demos/bad/draft/2009/after/home/ i have noticed that maybe an attribute label is missed from the form below. There is a label for the form (hidden text) but an additional label for the button "go" should be also included according to WCAG 2.0.   <form action="../../tmp/offsite" method="post" onsubmit="if(qkmenu.value=='0'){return false;}"><div><label for="qkmenu" id="qklabel">Explore Site by Topic:</label> <select name="qkemnu" id="qkmenu"><option value="0">Quick Menu</option> <option> Broadcasting</option> <option>Education</option><option>Electricity </option><option>Fire service</option><option>Gas service</option><option>Health care</option><option>Police service</option><option>Public Libraries</option><option>Social services </option><option>Social housing</option><option>Telecommunications</option><option>Town planning</option><option>Transportation</option><option>Waste management</option><option>Water services</option> </select> <input type="submit" value="Go"> Also the W3C CSS validator returned some errors in the web site.  regards Kostas---------------------------------------------------
