In the below function I got Summary total in column wise I need to show this sum to in footer template.
kindly help me to on this matter.

In Grid I am calling ClientSideOnLoad="Summary".


function Summary() {

var grid = eo_GetObject("Grid1");
var colCount = grid.getColumnCount();
var rowCount = grid.getItemCount();
var sum = 0;
for (i = 1; i < colCount; i++) {
for (RI = 0; RI < rowCount; RI++) {
var a = parseFloat(grid.getItem(RI).getCell(i).getValue());
sum = sum + a;

}
alert(sum);
sum = 0;
}
}
