I am using Moodle 2.0.3 and building a custom mySQL report. I have a number of fields being pulled up and put into columns which display fine. But when i go to the caculations tab it comes up with an error.

"Cannot access protected property average_form::$_customdata in \moodle\blocks\configurable_reports\components\calcs\component.class.php on line 37"

any idea on why?

or how would i use the custom mysql report with the caculations tab and the plot graphs tab?

the plots graph tab returns empty values in the drop down menu.
