Using numbers, I want to set up a formula to do the following: * If Column E = "Y," then subtract the value of column I from the value of column L. * If Column E is anything but a "Y", return a value of "0". I've never had to deal with a conditional in a formula before, and my searches keep revealing tips for conditional formatting. Any help would be appreciated. Thanks. UPDATE: Nevermind. I figured it out.
