Resolved: Introduction to Excel - Final Exam Question - Formula for Hiding Errors
Question no. 30 gives us 3 answers to choose from, IFERROR, ISERROR, and IFNA. I chose IFERROR and got marked as wrong because apparently all three work, but that is not true. File 'Multiple options', Sheet '6.', cell M14 shows the error '#DIV/0!'. Formula IFNA won't work because it is not an NA error.
