Test your form's design via the echo.cgi program
HTML and XHTML
Note: You can use your own form instead of this one, if you wish to experiment with other types of input fields.
Just remember to use the very same form action I have used in this form.
echo.cgi is written in Perl. In order to use echo.cgi on your own PC, you will have to install a web server and the Perl programming language.
Instructions for installing the Apache web server and Perl, both for MS Windows, are available
