I have 3 bits of data.

Ineed 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

After it has placed the EC-x into the fields i want to be able to
replicate the formula to check if there is a EC-x next to it to then
put a EC-1 and so on and so forth.
