No, as you have not explained what the problem is.

I'm looking for help with the first item. Then I will understand the rest. For example Adding javascript to the hamburger Quantity and price. I realize I have a hard time explaining myself.

what do you mean adding javascript to the hamburger quantity and price? do you need to total the values of items selected? you still have not explained what you are trying to do...?

for example if the hamburger is 2.99 and he enters 1 in the quantity field it will tell him it's 2.99 in the sub-total field. If he types 2 in the quantity field it will give him the sup--total of 2 hamburgers in the sub-total field.

mind you, I did not do the whole form, I did hamburger and cheeseburger fields along with subtotal pst, gst, and total fields near the end.
You were very vague on what you wanted so... I didn't quite understand until I was already coding, anyway, this should be a very good start for you.
If you want to move the 'total order' to the button, move the action to your submit button and call calculate_amount() there. hope the helps...

<script type="text/javascript">
	function calculate_amount() {
		var subtotal = 0;
		var hamburger_subtotal = 0;
		var hamburger = document.myform.hamburger.value;
		var hamburger_qty = document.myform.hamburger_qty.value;
		var cheeseburger_subtotal = 0;
		var cheeseburger = document.myform.cheeseburger.value;
		var cheeseburger_qty = document.myform.cheeseburger_qty.value;		
		var pst = 0;
		var gst = 0;
		var total = 0;
		//etc...
		//var chicken_burger;
		//var fries;
		//var gravy;
		//var chili;
		if (hamburger > 0) {
			hamburger_subtotal = hamburger * hamburger_qty;			
		}
		subtotal = hamburger_subtotal;
		// myform -- depends on the name of your actual form, if it does not have one give it one.
		document.myform.display_hamburger_subtotal.value = hamburger_subtotal;
		if (cheeseburger > 0) {
			cheeseburger_subtotal = cheeseburger * cheeseburger_qty;
		}
		// myform -- depends on the name of your actual form, if it does not have one give it one.
		document.myform.display_cheeseburger_subtotal.value = cheeseburger_subtotal;		
		subtotal = subtotal + cheeseburger_subtotal;
		pst = .07 * subtotal;
		gst = .05 * subtotal;
		// you cannot add the values after you call toFixed, so do the total now!
		total = subtotal + pst + gst;
		total = total.toFixed(2);		
		subtotal = subtotal.toFixed(2);
		pst = pst.toFixed(2);
		gst = gst.toFixed(2);
		//  this is wrong var tax = foo * 1.07; 	

		document.myform.display_subtotal.value = subtotal;
		document.myform.display_pst.value = pst;
		document.myform.display_gst.value = gst;
		//total = subtotal += pst += gst;


		document.myform.display_total.value = total;
		
	}
	</script>
	// first off this all needs to be wrapped in form tags if you are going to post the values to something.
	// you need to look up how to name your items, you should have an input type=x with name=y and id=y
