If option 1 is selected in Radio Button group A, then check option 2 in Radio Button group B.

I'm designing a form in which there are multiple sets of radio button groups: Types of Transaction & Methods of Payment.  The availability or applicability of some of the Payment options will depend on what kind of Transaction was selected and in the case of "Transaction Type1", there is only one available Payment Method: "Method2".  So I would like some help with the javascript that would select the Method2 radio button from "Method Radio Group" when a particular Transaction Type (Type1) is selected from "Transaction Radio Group".
