一个基于Excel中另一个下拉列表的下拉列表值

Question

I have two drop down lists in excel with same list of values (basically months of year which is fetched from a database, not relevant to the question here)

Now I want one drop down list value to change based on the value of another drop down list.

For example, consider that both lists contain values "Aug-2016" and "Jul-2016". If I select "Aug-2016" in one list the other list value should be "Jul-2016" (As in one drop down list value should be one month less than other drop down list value)

I know that it is possible through macros but any one knows if it is possible through excel formulae.

Answer 1

I found it. We can just use EOMONTH function in the second drop down list and that works.
