//1. Although the options for regular or waxed washing are checkboxes, when
//added to a CheckboxGroup... they essentially become RadioButtons...
//This makes sense though because you wouldn't really have both at once.
//2. The RadioButtons for the fuel use discounting have been locked to the appropriate states.
