The browser should send a 0, so I assume your problem is server-side.  The
PHP function empty(), for instance, will return true for 0 OR an empty
string (or if the variable is not set.) So, if the possibility exists that a
form field might contain a valid result of 0, you should check that field
specifically for an empty string using whatever tools your scripting
language provides for this purpose.

Has anyone run into the problem of a form entry of "0" (zero) not being
sent because the browser/cgi script interpreted an entry of 0 to mean
nothing was entered?

If so, is there a work around?
