I have a database of autos by make, model and year in columns. I need to create a drop down list by first choosing the make (no duplicates), then a dependent second list that would give me ONLY the models of that maker. Then finally a third dependent list of year for only that model. see attached spreadsheet.
Cells A2, B2 and C2 are where I need to make the drop down lists that are dependent on the previous list.
Thanks for any help that can be offered.
