Validating javascript?

[Jordie]

First of all, is it possible to code Javascript in valid XHTML (Transitional)? I'm stuck with validating an encrypted password script. This is the page, and following that is the code in question.

http://www.hexi-decimal.com/locked1.php

<script type="text/javascript">
//Encrypted Password script- By Rob Heslop
//Script featured on Dynamic Drive 
//Visit http://www.dynamicdrive.com 

function submitentry(){
password = document.password1.password2.value.toLowerCase()
username = document.password1.username2.value.toLowerCase()
passcode = 1
usercode = 1
for(i = 0; i &lt; password.length; i++) {
passcode *= password.charCodeAt(i);
}
for(x = 0; x &lt; username.length; x++) {
usercode *= username.charCodeAt(x);
}
//CHANGE THE NUMBERS BELOW TO REFLECT YOUR USERNAME/PASSWORD
if(usercode==16866649800&amp;&amp;passcode==1714036561020)
//CHANGE THE NUMBERS ABOVE TO REFLECT YOUR USERNAME/PASSWORD
{
window.location=password+".php"}
else{
alert("That doesn't seem to be right.")}
}
</script>

<center>
<div class="login">
<form name="password1" action="">
Username:<br />
<input type="text" name="username2" size="15" />
<br /><br />
Password:<br />
<input type="password" name="password2" size="15" />
<br /><br />
<input type="button" value="Click" onClick="submitentry()" />
</form>
</div>
</center>

I can actually get it to validate; I should have been more specific. I validated it and then when I went back to test-run the script, it wouldn't work. Please help.

Convert the HTML entities back to their normal character representations (i.e. & amp; should just go back to &), then move your script into a separate .js file. Call the file like so:

<script type="text/javascript" src="/encrypt.js"></script>
