This problem occurs, when you have a column with a formula that sometimes returns an error. That is very typical for all kind of look-up situations . Let’s say, you have a column E with formula that returns good values and errors. You need to count how many errors are in that column. Enter formula =SUM(IF(ISERROR(E2:E10),1)) and press Ctrl+Shift+Enter while still in editing mode. You should see two things. First, your formula turns into {=SUM(IF(ISERROR(E2:E10),1))} with square brackets around it, and second, you got you a correct cells with errors count. This is it. If you need to count cell without errors, you can use this formula: =SUM(IF( NOT( ISERROR(E2:E10)),1 ))…
