Just to follow up my previous post Stella

For what you are trying to achieve, there is no real simple answer.

The simplest way without going down the track of using VB coding is to
manually check each one.

Might be time to step up to the plate and have a crack at it, you will
always get better after each failed attempt.

There is always someone here in the NG's that will try and help you should
it get all yoo hard.

Good luck
Mark.
