Object doesn't support this property error

Object doesn't support this property error

Hi,
I have a table and it contains an asp .net Literal control. The literal control has some dynamic contents in it.

I was trying to hide this whole table on user action; e.g. when an icon is clicked. So I tried like:
  1.    img_crevents.click(function(){ 
  2.          if (tab_crevents.is(':hidden'))
  3.          {
  4.                   .......
  5.                   tab_crevents.fadeIn(delay_seconds);
  6.                   tabBottomContents.hide();
  7.          }
  8. })
But I get 'Object doesn't support this property' error.
How can I achieve this?
Thanks.
