I am trying to get the header grouping to work with the functions

jQuery(“#grid”).hideCol('Column3');

jQuery(“#grid”).showCol('Column4);

jQuery(“#grid”).showCol('Column5);

jQuery(“#grid”).showCol('Column6);

This works great in FF, Chrome, IE8, and IE9 however its not working at all in IE7…. Does anyone know why I can't figure it out at all.

The error I am getting is

SCRIPT87: Invalid argument.
