Return a list of Occurrences
 

I have a list of outages at our cell sites. It is an Excel Spreadsheet with 1
row of dat per outage. The spreadsheet has 1 month of data and could be over
200 lines. I'd like to create a formula that will tell me how many outages
were at any given site. Now, we have over 300 sites and not everyone of them
has an outage. Is there a formula that will review the data and return
something like:
Casco 3
Brussels 2
Abrams 4
Where the number would be how many times an outage occured at that site. I
only want to see sites with more than 1 outage in a month.
Any help would be appreciated (I've been pouring over help sites for hours!)

Return a list of Occurrences
 

A Pivot table could do this. Or, suppose you have a list of sites in
A1:A300. Then, you could use

=COUNTIF(DataSheet!C$1:C$200,A1)

and fill down from A1 through A300.

In this formula, it assume that: 1) DataSheet is the name of the
worksheet that lists the outages, and 2) that the sites on DataSheet
are listed in cells C1:C200. COUNTIF returns the number of items in
DataSheet!C1:C200 whose value is equal to A1. When you fill the
formula down the column, Excel will change the A1 to A2 then A3 and so
on down the range.
