I need to identify the correct function to achieve the following task:
Search specified column to find "22087", and count the occurences.

The problem I am having is that the cells within this column often contain
more than one numeric value in each cell. For example, contents of one
single cell may look like this: 22087, 22058, 22064. This cell identifies
the locations of all the jobs a candidate is willing to consider. If a
candidate is willing to consider placement in multiple cities/states, they
are all listed within the cell.
I need to know how many candidates are applying for each location #, and
CountIF only seems to work if the cells contain only one value. Help?
