Check Boxes, Radio Buttons, Multiple Select boxes and Buttons send nothing
to the action page on form submission unless at least one selection is made
or the button is pressed ... So if you have a checkbox named "mycheckbox",
you would want to ensure a value for that form field on the action page
using a <cfparam> tag
