Add specific columns

[NormanB]

I have a column that I want to place a "X" in some of the cells. This is a way to id certain rows. At the bottom of the column I want know how many cells in that column contain the "X". I know I could put the number "1" instead of the "X" and just total the column, but I do not want to do that. I want it to be able to put an "X" or some other letter in the cell and have the total number of cells with the "X" appear at the bottom.
