option buttons
 

Hi
I have a list of 11 option buttons and an enter button. Only one option
button can be checked at any one time. When I press enter I want all the
unchecked buttons to display a number 1 in a specific cell next to them, and
every time I press enter, 1 must be added to their total. The checked button
must be cleared back to zero when enter is pressed. Any help on this will be
appretiated.
