Hello I am trying to make a "Customize your new computer" spread sheet. I want the user to be able to select hardware upgrades from a drop down list which will automatically be added or subtracted from the total price of the computer at the bottom. I understand how to make the drop down list but not how to assign a value to the selected option. I don't have a lot of experience with formulas so I appreciate any help and please talk to me like a little child that doesn't understand very well
--Matt.
