Answer 5

if don't mind please write the code

Answer 6

Your add function should look like this:
function add() {
var form =document.getElementById("frmclac");
var n1 = form.elements.namedItem("txtn1").value;
var n2 = form.elements.namedItem("txtn2").value;
form.elements.namedItem("txtnans").value = eval(n1)+eval(n2);
}
It can't be nested in your calc function as it currently is.

Your form tag shouldn't have a name attribute. It requires an id="frmclac" instead.
