If the 1s and 2s are independent , then is not simply:

=Countif(A:A,1)+countif(A:A,2)

OR

=if(and(countif(A:A,1)0,countif(A:A,2)0),"both occur","only one or none
occur")

Or have I completely missed the point (again!)

Thank you for your help. I can count the number of times the number 1
appears in the column with no problem. My problems start when I try to count
the number of 1's and 2's that occur simultaneously. I will continue to work
at it.

I am trying to determine when I have repeats in a list of data. This is the
situation:

I have a list of data that contains numbers 1-99. I am trying to determine
when the numbers 1 and 2 appear in the same list and then count those
occurences. I have found a round about way of doing it, but do you know of a
faster way? Any help would be greatly appreciated. Thank you.
