I would like to count the number of times series of numbers appears in a column. For example: 123 is listed 2 times and 345 is listed 4 times. I would like to be able to sum the 2 (events)and 4 (events) for a value of 6 and place that value in a cell for additional use. Anyone know of a formula to do this? I'm trying to see how many times a ticket is responded to more than once during the reporting period.
