Dynamic Lists

I'm creating a sheet that requires a certain list to appear based on a value from an adjacent cell. So for instance I have 3 lists, depending on what value appears in a certain cell will dictate which list appears in the list cell.

I have named List1 in cell A3 using values in column L, List 2 in B2 using values from column M. The variable is listed in D2, this will impact which list should appear in D3. My problem is getting the actual list to appear (drop down).
