Tony, I can use that method to change some css of the class but not the color.

.rowselected{color: #ff0000; font-size:20px}

—-

jQuery(’#’+id).addClass(’rowselected’);
jQuery(’#’+lastsel).removeClass(’rowselected’);

If I click on a row the row changes to 20px font size and reverts if I then click a differnt row. That proves this method does change the css.

Unfortunately the cell color stays exactly the same instead of being forced to red.

Thank you Tony. All answers worked well.
