Price adjustment in multiple pieces.

[Yammaski]

I want to give a discount when the customer wants more than 2 of the same products.
The price shown must be the price minus the discount (see discounts on testpage).
There is also a "size option" which adjust the standard price of the product, this script works fine.
But my script for the discount doesn't work.

See testpage.

function getPrice(option, prodPrice) {
var prodPrice = parseFloat(prodPrice.replace(",","."));
var thePrice;
  switch (option) {
    case '10':
	  thePrice = (prodPrice-1).toFixed(2);
	  break;
	case '15':
	  thePrice =  prodPrice.toFixed(2);
	  break;
	case '20':
	  thePrice = (prodPrice+2).toFixed(2);

	  thePrice = (prodPrice+4).toFixed(2);

//DISCOUNT : 1-2 pcs : no discount  ***  3-5 pcs : -20%  ***  6-9 pcs : -30%  ***  > 10 pcs : -35%

 return (thePrice.toFixed(2)+'').replace('.',',');
}
