I have a vehicle intake-form in which users have to enter vehicle data.
I also have a huge list containing make/model information.
I would like to be able to use this database in the following way : I want the user to select the make in cell A1 , and then the model in cell B1. It must be possible to choose for example the make "BMW" in cell A1 and then cell B1 should only display the BMW models, and not all others that are present in the list...
I tried to use Data Validation with a list of choices, this works fine for the make (A1) ; but how do I make the list used for Data Validation on B1 dynamically related to the value in cell A1 !?
Any help would be much appreciated.
