They will disappear when you edit the formula.Įxplanation: The range (array constant) created by the IF function is stored in Excel's memory, not in a range. Note: The formula bar indicates that this is an array formula by enclosing it in curly braces. To achieve this (don't be overwhelmed), we add the SUM function and replace A1 with A1:A8 and B1 with B1:B8.Ģd. All we need is a SUM function that counts these 1's. So the third row will be counted, etc.Ģc. For row 3, the IF function evaluates to IF(FALSE+TRUE,1,0), IF(1,1,0), 1. For row 2, the IF function evaluates to IF(FALSE+FALSE,1,0), IF(0,1,0), 0. For row 1, the IF function evaluates to IF(TRUE+TRUE,1,0), IF(2,1,0), 1. We use the IF function to check if Google or Stanford occurs.Įxplanation: TRUE = 1, FALSE = 0. Rows that contain Google and Stanford are counted twice, but they should only be counted once. However, if we want to count the number of rows that contain Google or Stanford (two columns), we cannot simply use the COUNTIF function twice (see the picture below).
