[ic] Adding a required field to the checkout.html page

[Bryce Tom]

How do i add a required field to the checkout.html page?  i want to have it
appear in bold, display an error message when its not filled in, and have
the field displayed in the receipt page, and the online order email. i've
set required equal to 1, but its still not working.
