It seams that PHP isn't set to process the vars. It is needed to change
the php.ini in some place where there is the following:
; You should do your best to write your scripts so that they do not require
; register_globals to be on; Using form variables as globals can easily
lead
; to possible security problems, if the code is not very well thought of.
register_globals = Off
For your script to work as is, replace the Off with On.
However, bear in mind the security problems, because it very easy to
"emulate" a web page and feed it with the data one wants.
I would recomend that you use the arrays $_GET and $_POST to get the
specific var (depending on the method used in the form page) and more,
perform a expretion evaluation with regarding to the vars values (to
ensure that the values are ok (like be numeric so the multiplication
with the unit price will give the correct ammout).
Be ware also that when "re-posting" the data for the execution page,
never reuse totals and values processed by the previous page... because
would be easy to send a $1 dollar bill for all those stuff in your store!
