How do I 'total cost' items in a shopping basket?

Here is my JavaScript code to date, apologise that it is so simple I am a beginner! I'm sure this could be written with half the code but then I wouldn't understand it! lol

var A = 0; var B = 0; var C = 0; var D = 0; var total = A + B + C + D;

document.getElementById("1").onclick = name1;

function name1() { document.getElementById("product1").innerHTML = "Great Ocean Road"; quantity1(); }

function quantity1() { document.getElementById("qty1").innerHTML = "1"; cost1(); }

function cost1() { document.getElementById("price1").innerHTML = "£360.00"; quantity1(); }

document.getElementById("2").onclick = name2;

function name2() { document.getElementById("product2").innerHTML = "Blue Mountains"; cost2(); }

function cost2() { document.getElementById("price2").innerHTML = "£420.00"; quantity2(); }

function quantity2() { document.getElementById("qty2").innerHTML = "1"; amount(); }

function amount() { document.getElementById("amount").innerHTML = total; }

I can't get the values of the items inside the variables? I was then going to add them together at the end?

I think you need to think through the steps some more, and give us some hints on what you are trying to do, step by step. Adding some comments in your code might help us help you.

The way it reads right now:

  1. Set up vars A thru D equal to 0. Sum them in var total (total=0)
  2. When user clicks on element id #1, populate the product, quantity, and price.
  3. When user clicks on element id #2, populate the product, quantity, price. Also set the amount to total (0)
