something on these grounds:
<HTML>
<HEAD>

<script Language="JavaScript">

function checkPassword () {

      var strng  = document.passwordResetForm.newpass.value;
      var strng2 = document.passwordResetForm.verifypass.value;
      var errMsg = "";
      if (strng == "") {
            errMsg = "Enter a password.\n";
      }

      if ((strng.length < 6) || (strng.length > 16)) {
            errMsg += "The password is the wrong length\n";
      }
      if (/[^a-zA-Z0-9]/.test(strng)) {
            errMsg += "The password contains illegal characters.\n";
      }

      if (!/[0-9]/.test(strng) || !/[a-zA-Z]/.test(strng)) {
            errMsg += "The password must contain at least one letter and one numeral.\n";
      }

      if(strng!=strng2)
            errMsg += "Your passwords do not match!\n";
     
      if(errMsg==''){
            return true;
      } else {
            alert(errMsg);
            return false;
      }
return false;

}
</script>

    <title>Password Reset</title>

</HEAD>

<body>

<FORM NAME="passwordResetForm" ACTION=" " METHOD=post onsubmit="return checkPassword()">


           Enter New Password: <input type=text name=newpass value=""><br>
               Verify Password: <input type=text name=verifypass value=""><br><br>

             <input type=submit value="Reset Password"><br><br><br>
