Enter the name of this radio button. If you have several radio buttons which act as a group, use the same name for each button. For example, a form allows a choice among three colors such as "Red", "Green" and "Blue". Set the values of the radio buttons to "Red", "Green" and "Blue" respectively but set all three names to "ItemColor". So when the form is submitted, the name "ItemColor" will go with the value of the selected radio button.
