ican't figure it out if this textbox, label or what.

Use javascript or jQuery to add every rows totalrate value and show it in a total value. Providing some code may help to fix ur problem.

At some point, unclear in your code, you are multiplying qty x rate for each item, so $item_total = qty x rate; although, I do not see this in your code here. anyway I am assuming this is happening in your while loop as you are doing each item. so prior to your while loop make a new variable $grand_total = 0;
inside your while loop after $item_total is calculated do this:

$grand_total += $item_total;  // <-- wherever $item_total comes from.
// when you want to display it, $grand_total should hold the values of all items.

Hi

Thanks for your reply.

i have done the multiplication through Java script the code is below

<script type=text/javascript>
function multiply(id){
var a;
var b;
var c;
a = document.getElementById("rate" + id).value;
b = document.getElementById("required_qty" + id).value;
c = a * b
document.getElementById("total_rate" + id).value = Math.round(c*100)/100;
}

function getSum(){
                
				var val=document.getElementById("total_rate" + id).value;
                var sum=0;
                for(var  j=0;j<val.id;j++){
                    val=parseInt(val[j].value);
                    sum +=val;
                }

                alert("total is ="+sum);
               // str+="<span><input type='text' value="sum" /></span>";
            }

</script>

and i am trying to find out sum through getsum function as above.

Help me
