I have try to change return String(total) with return total.toString(), but it's still Null return..
Or, maybe I did null value in here : arrDataTranskrip[i][col.dataField] I try to modify this code like this : total = lengthArrayDataTranskrip; and it's working. I build this function to get a total sum from field in DataGrid that have dataProvider as Array.
