Wow that is amazing! Ok im not sure whether this is the norm, but would it be possible to explain how this formuale works, so that in the future i do not need to refer to the forum for help, and might even be able to contribute more to helping others on this forum.

As i said im not sure if this is normal practice or not, but i really need to learn about these array formulae, or even point me in the direction of where is best to learn about them.

Anyways your reputation has jus been boosted many thanks Ad
