If I understand you correctly, you either want to use radio buttons (if you want to allow only one choice from your presets to be selected) or checkboxes (if you want to allow any number of presets to be selected).

You can refer to the parts of the CGI man page that describe "CREATING A RADIO BUTTON GROUP" or "CREATING A GROUP OF RELATED CHECKBOXES" (to be found under "CREATING FILL-OUT FORMS").

In either case, all "preset" buttons are associated with a single parameter, and the value of that parameter will depend on which radio button (or which checkbox(es)) the user clicks before hitting the "submit" button.
