I am looking for some assistance with the isPair function. The function should tell me if there are two pairs in the 5 values. It is only robust enough to tell me if there is 1 pair.
I am trying to find if there are two matches of values 15 in the same columns in a 4x10 2D array.

There are numbers valued 15 randomly placed in the 2d array and I need to know if two sets are in the same column.

The remaining columns are rows are filled with the last 35 values, also randomly inserted throughout the rows and columns.

In the following example, I have inserted some ‘dummy’ data to test my output. The code successfully tells me if I have 1 match, but not if I have two matches.

This is hopefully clearer!
Pls note that this is not a search to find matching values in an array column  rather two see if there are two matches of the 15 values in the array.
Thx! Karen Stumped
