Setting Radio Button properties in other groups

Question

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
