Never, ever, accept code from a insecure website to handle anything to do with real money.
You do not know who is giving you the code, you do not know what it does, you do not know that it places the monies correctly into the appropriate account, without passing the details to any third parties.

Only get such code from Paypal - the scope for fraud otherwise is far too large. And remember, you personally could be liable for any monies lost if your action is seen to be negligent - which getting your code from a public forum would most certainly be!

Seriously: this is not an area where learning to do basic stuff as you go along is a good idea. Practice and become proficient in all other aspects of web design and coding (especially the security implications) first. You could end up seriously out of pocket here, or even in jail if you don't do the job professionally.

i have solved my issue on my own

the solution is to add a javascript function and call it

Here is the modified code

<script>
function MyScript()
{
var x, y;
x = document.getElementById('<%=Label1.ClientID%>').innerHTML;
y = document.getElementById("amt").value = parseFloat(x).toFixed(2);
}
</script>

<form id="form1" runat="server" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="abc@gmail.com">
<input type="hidden" name="item_name_1" value="Aggregated items">
<input type="hidden" name="amount_1" id="amt" >
<input type="submit" value="PayPal" onclick="MyScript()" >

<div runat="server">
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</div>
