When working with forms, you might want to add multiple groups of radio buttons.

For example, one group might choose the color of a car and the other group might choose the make of the car.

Our goal is to allow the user to select one radio button from each group. To do this, all we have to do is make sure that the first characters of the radio buttons' VARIABLE NAMES are the same for each group designation.

So in the example, one might name the "color" group's items cradio1, cradio2, cradio3 and the "make" group mradio1, mradio2, mradio3.
