Okay, I want to be able to select something from a drop down menu and when I do, populate several cells with information from another worksheet that corresponds to the item in the drop down menu. Is it possible to do this without having an extensive formula in each cell I want to change?
It's not terribly difficult. You have to put a validated list of data in the cell with the drop down. (Data/Validation from the menu). Say, A,B,C as your possible choices.
Then somewhere (another sheet?) you build your response table:
Sheet "test"
A 10
B 20
C 30
(in the above A,B,C are your drop-down choices)
Then in the cells where you want to place the data that corresponds with the dropdown choice, you enter a VLOOKUP formula to find the number that corresponds with each of the potential dropdown choices. See
