Drupal 7 - div popup inside the overlay (node/123/edit) I'm trying to display a pop up dialog (using a hidden block) inside the overlay when editing a node.

When i click to edit a node, the overlay appears with all the custom fields of a given content type as usual. It is clean and white and everything in the background is darkened out.

So now i have logic in place (using jQUery) that's supposed to change my div's display to 'show' on keyup for a specific field on top of the overlay edit node.

I've tried adding a z-index of over 1000 and still nothing. The drupal overlay is using a z-index of 501 but my custom div still wont display on top of/over it. 

This is my CSS for the hidden block:

#block-block-block-26 {
  z-index: 2000 !important;
  position: fixed;
  display: none;
  text-align: center;
  border: 1px solid #333;
  width: 200px;
  height: 80px;
  border-radius: 5px;
  padding: 10px;
}


This is my function inside jQuery:

 $('#edit-field-pi-estimated-ini-capital-und-0-value').keyup(function() {
        var txtVal = this.value;
        if(txtVal == 0 &amp;&amp; txtVal != '') {
          $('#block-block-block-26').show();
          return false;
        }
  });


any idea how to make my div appear over the overlay?

Thanks
The code is fine, problem was with jquery version.
