blockui Popup doesn't popup

blockui Popup doesn't popup

Using jquery.blockui.js  I have the following in a javascript function but the popup never occurs.  It displays the Alert("AAA") & Alert("BBB") but never displays the blockUI popup.  It doesn't show an error so I don't know what I am doing wrong.  Thanks.


"AAA" );

function () {


      centerY: 0,

      css: { top:

'10px', left: '', right: '10px' }


      setTimeout($.unblockUI, 2000);



"BBB" );
