Radio buttons – reset only one button that is part of group of two

Hi Guys

I need some help with an interactive form I created in Acrobat.

Above is a screenshot of the area where I'm having issues.

I have two radio button groups.

Group 1 = Card button or Cheque button

Group 2 = Visa button or MasterCard button

I have used actions to reset some buttons but I'm looking for an action to check buttons!

For example if somebody clicks on the MasterCard button first without clicking on the Card button, then I would like the Card button to check itself.

Similarly, if somebody clicks on the Visa button first, then the Card button will check itself.

Also I would like to reset just one button that is part of Group 1 – is this possible?

I would really appreciate any help!
