In general, server side scripting is when you submit your form and then the
resulting page checks if you've filled in everything correctly.

A cryptic example:

----
if [ form.firstname = "" then go back to previous page ]
else [ mail form.firstname to me(at)myhost.com ]
----

So... if they didn't fill in their name (the "firstname" field of the form)
they will be taken back and they will get a message to fill in their name.

If they did fill in the name, it will be sent through email.

Believe me, in practise it requires some more lines and other commands and
probably you have some more form fields, but I think this explains how it
works.  The thing is it's the server who checks if the data is correctly
filled in, and since the user generally doesn't control what happens on the
server and also doesn't require you to have some browser plugin installed,
it will leave less room for errors etc...

They're talking about using something like I sent (personally, by accident).
To add to your perl script.

$MyVariable = param("field_name");
 if (! $MyVariable) {
print "<h1>HEY, HOW CAN I SEND THE ITEM IF I DO NOT KNOW YOUR
ADDRESS??</h1>\n";
print "<br><a href=form.html>Go Back</a>\n";
exit;
}

# The "$MyVariable = param("field_name");"  might be "$MyVariable =
$FORM{'field_name'}".  You can see how
fields are specified by looking at your script code.

The "!" means "not" to perl.
