How to use functions in one cell to get text in another cell

Hello. I need help with what I thought was a simple "If, Then" type of
function. I would like to use functions to fill information in another cell.
My problem is that the first cell has a possibility of 12 different options
which would then result in a value. (So 12 options = 12 different values.)
Is this possible or can you tell me how to accompish this task?
