	var subTotalField = dojo.byId("m4j-181");
	var vatField = dojo.byId("m4j-184");
	var totalField = dojo.byId("m4j-186");
	
	subTotalField.disabled= "disabled";
	vatField.disabled= "disabled";
	totalField.disabled= "disabled";

	qtyField.value = qtyField.value || 1;
	amountField.value = amountField.value || 0;

	function calculate(){
		var qty = parseInt(qtyField.value) || 1; 
		var amount = parseFloat(amountField.value) || 0;
		var subTotal = Math.round(qty * amount * 100)/100 ;
		subTotalField.value = subTotal;
		var tax =  Math.round( ( subTotal / 100 * 19) * 100)/100 ;
		vatField.value = tax; 
		totalField.value = ( subTotal + tax );
		
	}

	dojo.connect(qtyField,"onkeydown",calculate);
