function CalculateTotals() {
var gv = document.getElementById("<%= GridViewBill.ClientID%>");
for (var i = 0; i < gv.rows.length - 1; i++) {
var Bags = $("input[id*=TxtBags]");
var weight = $("input[id*=TxtWeightBags]");
var totalamount = Bags[i].value * weight[i].value;
alert(totalamount)

if (!isNaN(totalamount)) {
document.getElementById('TextBox1').value = totalamount;
}
}
Getting Error not able fetch the data into QUantity box in gridview..
