I have an Excel 97-2003 worksheet that has radio button controls. In design view, when I right click and pick Assign Macro, I see a macro named, for example, OptionButton8448_Click, but there is no way to edit the VBA code. The radio button does indeed causes cells to update, so there must be VBA code firing somewhere. My quesion is: how do I get a the VBA code behind the radio button? thanks!
