echo $html->link( "SOME TEXT" , array('controller'=>'modules', 'action'=>'grade', $varOne,$VarTwo), array('class'=>'button'));

Hi i am trying to pass two variables to my controller when my user clicks a link.

Is that possible?

usually when i put a single variable i can just put function grade($id = null) and access my variable through $id, but how will i access my second var in this case? thanks!
