In my view fill I have the following code:
"grouping"=>array(
"username"=>array(
	"calculate"=>array(
        	"{sumHours}"=>array("sum","hours"),
	),
											
	"top"=>"<b>User Name {username}</b>",
	"bottom"=>"<td><b>Totals </b></td><td></td><td></td><td></td><td></td><td></td><td></td><td><b>{sumHours}</b></td>",
					
),
),
I need to also calculate the sum for 3 other columns in the report. Is there a way to do this?
Any help would be greatly appreciated
