getting my 1st query to work

getting my 1st query to work

Hi,
Trying to work out why this query wont work. Some background is that the site is a DNN site with a specific forms module. Its common practice for knowledgeable users to insert jquery but I just cant seem to get mine going.

As a starting point, I just want to hide a field & label that sit in their own row.

Thanks to a member I have determined that the page is running 1.9.1

Code I have used is (I think the system puts in (jQuery);). Below that is the row that is being referred to.
  1. </script>
  2. <script type="text/javascript">
  3. (function($){
  4. $(document).ready(function(){
  5. $("#UnknownCategory").hide;
  6.  });
  7. })
    (jQuery);
    </script>
  <div class="xmp-form-row-jquery"><Label CssClass="xmp-form-label" For="UnknownCategory">Unknown Category</Label><TextBox Id="UnknownCategory" Width="200" Nullable="True" MaxLength="50" DataField="UnknownCategory" DataType="string"></TextBox></div>
