You have the order reversed. Ideally, you should give each input the same name with a different value. The reason for that is one of maintainability. If you have different names, you generally have to write code to handle each name. However, in a well-designed app, if the only a new value is added, you may not have to change the code:

  Football: <input name="sport" value="football" type="checkbox" /><br
+ />
  Baseball: <input name="sport" value="baseball" type="checkbox" /><br
+ />
  Soccer:   <input name="sport" value="soccer"   type="checkbox" /><br
+ />

With those three inputs, you can often use just one basic line to handle them:

  foreach my $sport ($cgi->param('sport') {
    # do something with sport
  }

If handled correctly, adding a new sport is now just adding a new input box. By using different names, I'd like have to write a new input box and write new code.
