HTML Form question

I have this as an option field:

<option value="5">Business Objects Support</option>

Is the "value" what gets passed back? In this case "5"?

I have no idea what you think this question has to do with Perl. This
is purely an HTML question. Regardless, yes, the 'value' is the value
the <select> input will have when the form is submitted

<select name="foo">
<option value="alpha">one</option>
<option value="beta">two</option>
<option value="gamma">three</option>
</select>

When this form is displayed on a browser, there will be a drop down box
with three options: one, two, and three. If the user selects "two"
and submits the form, the form variable "foo" will have a value of
"beta".

The associated *name* and *value* are passed on to the Perl script if
you are pointing your form to a Perl script. For example, you have a
drop down list of 10 options like your above example, and the name of
the NAME of the form was BUSINESS TYPE then your Perl script would
read the form data as such:

$FORM{BUSINESS TYPE} = 5;

Only if you're using ancient perl4-style CGI modules. The modern CGI.pm
decodes this using the "param" function:

my $value = param('BUSINESS TYPE'); # returns "5"

Please don't answer other CGI questions until you've come up to at
least the mid-90's. Thank you.
