dhtmlxGrid footer doesn't work


I try enable footer on the grid as explained on example in your site. unfortunately its doesn’t work.

here the code of page. its not show any data after loading. original page without footer is work. see look on the second tab.

div.gridbox div.ftr td{



border-right:0px solid gray;


div.gridbox_light table.hdr td {




whats wrong?

Your sample returns error:
dhxTabbar is not defined
Line 174
Also note, attachFooter() method is available in PRO version only.
