If you are human just like us, sooner or later you will make an errort and
will need this function...

Seriously, ISERROR is used to suppress or take an alternate action if the
formula being tried generates and error. It is also used when many functions
are used together to build a large one. If any piece retruns an error the
whole fails. By testing for ISERROR one can recover from such situations.

Why would I ever need this function?
