Col A already exists and I want to take first item in Col B and search all
of Col A for that item. If it does not exist, return either a "no" or a "0".
If it does exist, I want to know where it is in Col A so I guess that I need
the cell location returned. All returns can be returned to the next column
over next to the item I am searching for Then move to the second item in Col
B and search all of Col A again for that item with same results, Then move to
third item in Col B and so forth.
