Hi,

I have a table with several rows and columns of information. I will
continue to add new information new rows and I want to make sure that I never
have duplicate a row.

So here is a simple example:

A B C
1 i 1 k

2 r 3 n

3 a 2 f

4 a 1 f

5
I want to be able to add another row of information and if the array in that
row from columns a to c matches an array I already have I want to be notified
and it would also be nice to know which array I am duplicating.

Can anyone help?

Thanks,
John
