Hello,
Yes this will be possible but please explain further, you say you want comboBoxes filled with this info but don't wnat to use a userform, do you want a combobox embedded in the spreadsheet?
Also suppose column A has a list of countries, where would the list of the cities within that country be. You must be relating the cities to the country somewhere.
If I was to select country "Argentina", where would you look up the cities that are in "Argentina". If you have a list of cities then how do you determine which city belongs to which country?
A screenshot of your Countries and Cities data would help solve the problem.
