here using count addrow id rows are generated dynamically this below function only gives sum of first input field which is static and second which is dynamic in third field its giving sum of 1st and 3rd field help me with this we are new to JS?

What I have tried:

function calTotal(sum) {
	var w=0;

	var sum = Number(document.getElementById("total").value) + Number(document.getElementById("total"+w).value);
	// var sum1 = sum + Number(document.getElementById("total"+w).value);
		document.getElementById("sub").value = sum.toFixed(2);

Your function calculates the sum of the fields at id total and total0. That is all.
