Changing field names thro code

[Razor]

Hi,

I have a form that has a listbox for the user to select a
name and runs report on certain identifiers that are
associated with the chosen name.

I have another pair of columns that have this same name-
identifiers association.

I want to be the form's VBA to read the selection on a
radio button to know which pair of columns to use.

Currently, I go into the table's design view and change
the names of all 4 columns (both pairs) each time I want
to change over.

How would I implement this using the radio button?

Thanks,

Razor
