Setting Radio Button properties in other groups
                            
                         
                        
                     
                 
                
                    I would like to set radio buttons in other radio groups when a radio button is selected.  There are different groups that I wish to turn off when a radio button from another group is selected.  Simply stated, I would like to set the checked property of other buttons to false. Or better yet set an entire group to false.  For example if I had the following two groups:
 o  group1 option button 1                                     o  group2 option button 1 
 o  group1 option button 2                                     o  group2 option button 2  
If group1 option button 1 was selected I would like to turn off the entire group2 or visa versa.
Turning off each group2 radio buttons would work too.  
Thanks
