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

Had some time to play. About 10 mins and round 50 lines of js. Not showing off, just saying it's not very difficult (beginner level) and that you should have a go yourself before asking for a complete solution: http://screencast.com/t/au5VGbkb
