Radio Buttons - Need help with Marco/assigning use

[montanaaggie]

I have radio buttons in the following cells. a2, a3, a4, a5. I have equations next to them respectively in cells b2, b3, b4, b5. I'm not familar with VB, so I am looking for code for the following: What ever radio button I select I want to be associated with its repective equation a2 paired with b2. I then want the selected equation to appear in cell "a1" So if I selected a3 button, it'll take the equation from b3 and display it in a1. Thanks.
