Need VBA code to hide cells if radio button in another cell is chosen

Here is the file in a 97-2003 version Jerry. Scenario: I hit the radio button in cells A16-C16 and choose a date from the pull down calendar in cell E16; it will then populate cell D16 with the date. When I do this, I would want cell I16 to be hidden because I don't need a SUPPLIER DUE DATE if it is a parts order and vice versa.
