Validation no longer working...old version though. :(

The form validation on an old form has stopped working. It's an old classic ASP website though so I can't use the extension anymore on it but I wondered if you could spot anything obvious...

Here is the form tag info:

<form action="music-events-search.asp" method="post" name="eventsearchform" id="eventsearchform" onsubmit="WAValidateRQ(document.forms[0].sdate,'- Please enter a start date.',document.forms[0].sdate,0,false,'text');WAValidateRQ(document.forms[0].edate,'- Please enter an end date.',document.forms[0].edate,0,false,'text');WAValidateDT(document.forms[0].sdate,'- Invalid date.',true,/.*/,'','','',false,/.*/,'','','',document.forms[0].sdate,0,false);WAValidateDT(document.forms[0].edate,'- Invalid date.',true,/.*/,'','','',false,/.*/,'','','',document.forms[0].edate,0,false);WAValidateRT(document.forms[0].k,document.forms[0].k.value,'- Invalid content in your keyword search.','%7B|%7B, %7D|%7D, %5B|%5B, %5D|%5D, //|//, :|:, ;|;, (|(, )|), =|=, +|+, _|_, http|http, http|http, %5Burl|%5Burl, /url%5D|/url%5D, %25|%25, $|$, #|#, %5Blink|%5Blink, /link%5D|/link%5D',document.forms[0].k,0,false);WAAlertErrors('The following errors were found','Correct invalid entries to continue',true,false,false);return document.MM_returnValue">

And here is the client validation code:
