title: Adding multiple if statements together
body: <p>I'm making a spreadsheet with different books people have to read and when the person gets finished reading the books they will mark and x and the box. So I have a formula for the following book columns E3,G3,I3and K3 which is COUNTIF(B3:L3,"X")*20. Can I add this formual to another so that N3 and O3 are worth 2.5?</p>
