I can't figure out how to count occurrences of a wildcard matching certain
criteria. For example, let's say I want to count the number of cells
containing words ending in "ing" - even if those cells contain other words
besides the one ending in "ing". How do I do that? And then, out of that
count, how do I count only the number of those cells which also contain a
value of "X" in the same row one column to the right? Let me give a visual:

A B C
1 slow ending X
2 slow beginning X
3 fast ending

In this example, there are 3 cells in column A that contain a word that ends
in "ing", and out of those 3, 2 of them have an X in column B. What formula
would I use in this situation to account for the wildcard *ing, and to count
only those occurrences that also have an X in column B, to give the value of
2 in the cell containing this formula?
