Unfortunately, a "typical" form mail script is simplistic: it just collects
data and sends it as an e-mail message. But if you have control over the
script (i.e., you can write it or modify it or make someone else to do that
by your wishes), it can of course perform a simple check on any field or on
selected fields, ignoring (for example) fields with a value of 0. It's just
an if statement, or some if statements.
Independently of this, a field for inputting a quantity would probably be
better handled using a text input field rather than <select>. For one thing,
it's faster to type in "1" (or some other number) than to select "1" from a
dropdown list. Moreover, this approach lets any quantity to be entered by
the user. This might be seen as a problem, too: you need to check the input
data in the form handler or elsewhere. But that should be done anyway.
Using text input fields, the problem would be slightly different, though not
more difficult: the form handler's if statement(s) would not check against a
value of "0" but against the empty string "".
