Solution 3

I bet it's having a problem with document.getElementById (because javascript is client side, and the aspx page is server side?). Try putting the script into the <head> section of the masterpage.

Hi,

I see the document.getElementById("") properly.Otherwise you can Take TWO HIDDEN field in you aspx and assign
Sum and Subtract value to hidden field like this,

document.getElementById("ctl00_ContentPlaceHolder1_FirsthdfID").value = sum;
document.getElementById("ctl00_ContentPlaceHolder1_SecondhdfID").value = substract;

and Access this HiddenField value from your Code Behind ,

txt4.Text=FirsthdfID.value;
txt5.Text=SecondhdfID.value;

All d Best.
