Hi All

I need it to check the entire column to see if any of the data
matches
and it so provide a EC-x in the appropriate col so in the example
below.
Col1 Col2 Col3
Row 1 EC QWERTY POIUY
Row 2 (EC-x) ZXCVB QWERTY
RO3 EC lkjhg ZXCVB
.....
Row 4 (EC-x) rtyui QWERTY
Ro4 (EC-X) asdfg lkjhg

Once i have done that i need it to do the same but this time where
there is a EC-x to put in a EC2 and then again once thats done to do
an EC-3.

Happy to do this multiple time using a formula.. but not sure of how
to do this via a formula or even a bit of code... anyone help?

That's not very clear. Are you trying to count occurrences in Col2 and
Col3 separately or both? Is EC-x in Row 4 suppose to indicate the
number of occurrences of "rtyui" or "QWERTY"?
