[SOLVED] Table Hide function error

Hi, I've made a form for my users to edit their personal details once they are registered. This includes a section called NUS and NUS Number (National Union of Students in UK) and every time the user clicks on the NUS check button it hides/unhides the NUS Num section below it.

 

Now what's wrong with it is that if the user has selected NUS it activates the checkbutton and fills out the NUS Number field, but for some reason it stops the check button from being clicked on and using the function again. This produces no errors in my Error Console in Fire Fox and the strange thing is that if the user doesn't have NUS selected prior to this then the check button and function works fine.

 

Here's the function code:

 

function NUSHide(f){
   var mode;
   <?php
   if($Cont == false)
   {
      if($NUS == 1)
      {
         ?>
         document.Edit_Details_Form.NUS.checked = true
         mode="block";
         <?php
      }
      else
      {
         ?>
         if(document.Edit_Details_Form.NUS.checked == true)
         {
            mode="block";
         }
         else if(document.Edit_Details_Form.NUS.checked == false)
         {
            mode="none";
    document.Edit_Details_Form.NUSNum.value="";
         }
 <?php  
      }
      ?>
      return document.getElementById('NUSHide').style.display=mode;
      <?php
   }
   else
   {
      ?>
      return false;
      <?php 
   }
   ?>
}

 

and here is the form code with the NUS part at the bottom:

 

<body onLoad="javascript:NUSHide(document.getElementById('NUSHide'));">
<div class="MainContainer">

<?php require('admin/header.inc');
require('menu.inc') ?>

<div class="DivMain">
<?php
if($Cont==true)
{
   ?>
   <span class="head2"><?php echo $MsgEdited?></span><br><br>
   <a href="my_account.php">Back to My Account</a>
   <?php

   $conn = mysql_connect($Host,$Username,$Password) or die(mysql_error());
   $db = mysql_select_db($Dbname, $conn); 
   $sql2 = "SELECT Email FROM UserAccount WHERE UserID='$EditThisUser'";
   $rs2 = mysql_query($sql2, $conn)or die('Problem with query: ' . $sql2 . '<br />' . mysql_error());
   $row2 = mysql_fetch_array($rs2);

   $Email = $row2['Email'];

   mysql_close($conn);

      $message="";
      $message=$message."<html>";
      $message=$message."<body>";
      $message=$message."<span style=\"font-family:Comic Sans MS; font-size:24pt; text-align:center; background-color:#E61732; color:white; font-weight:bold\">A&WC Clothing Line</span><br>";
      $message=$message."This is a confirmation that you changed your account details.<br><br>";
      $message=$message."Your new Password is: $NewPass"."<br>";
      $message=$message."If you were not the one responsible for changing this password then please contact The Hub immediately and we will try to sort the problem out for you.";
      $message=$message."</body>";
      $message=$message."</html>";
  
      if (mail($UserEmail,"$User - Change Account Details Confirmation - A&WC Clothing Line",$message,"Content-Type:text/html;charset=us-ascii")) {
         $MsgChange= "Your password has been changed successfully!";
      } else {
         $MsgChange= "Can't send e-mail on this system... Doh!";
 die();
      }
}
else
{
   ?>
   <span class="head2">Edit Account Details Form</span><br>

    </form>
    <br><br>
    <a href="my_account.php">Back to My Account</a>
    <?php
}
?>
</div>
</div>
</body>

 

P.S. $Cont is only used after the form has been submitted successfully so I added that to stop the undefined function error.
