Customer Display Html question

I have a question for the tutorial from here: Customer Display using Custom Browser Printer

How do I add a Subtotal/Tax/Total line on the bottom?

Look at the Template Help on the right side. Use the applicable Tags to get what you want, such as:

Subtotal:{PLAIN TOTAL}
TAX:{TAX TOTAL}
TOTAL:{TICKET TOTAL}

I think he want to move from top to bottom. I think it just cut and paste to footer section.
