MDL-14663 "link_to_popup_window displays 'Click here....' as the link text if you pass in 0 as the link text." Solved this by formatting the grade using number_format to display the grade with a number of decimal places. So for 0 we display something like 0.00 and this displays OK in link_to_popup_window.
