Order Form will not display any dollar amounts after Submitting

[system]

I am working on a school assignment and whenever I hit Submit in my HTML page to continue onto my PHP page, it won’t show the correct dollar amounts. It will only show $0 and I have no idea where I am going wrong. I’m quite new to this and the class is a college course that is online so I cannot easily/directly ask the professor. Help!

HTML code:

Book Sale

Hi,

You can use builtin number_format() function of PHP. So to display your $subTotal:

echo "Your sub total is: ". number_format( $subTotal, 2, ‘.’, ‘,’);

It should display something like $1,234.56
