Using a text box might actually be a better option, especially since it
allows the user to order several copies of a product. Whether the text box
should be initialized to "0" or to an empty string is debatable. I'd vote
for the empty string (value="", which is the default), since it makes it
easier to the user to review his order.
Why would you use a checkbox? Admittedly it is faster when using the mouse,
since you can click on the box (if you can - many people suffer from motoric
disabilities that make it difficult to hit such a small box), as opposite to
clicking on a field and pressing "1". On the other hand, people who fill out
a form efficiently, using the keyboard only, using the tab key to move to
the next field, have no essential difference between the two ways.

Most probably you have named the elements wrongly. The checkboxes need to
have unique names. If you post the URL, probably someone will tell what's
wrong there.

On fundamental difference is that if a checkbox has not been checked, it
does not contribute anything to the form data set. A text box always
contributes at least the string consisting of its name and the equals sign.
