Larry, just to clarify a couple of the reponses you have had, only your question was slightly
ambiguous in that you could interpret it two different ways:-
1) Chip has given you a solution that will count every cell that has 1 and only 1 in it. 11 in a
cell would not get counted as 2, in fact it would not get counted at all (Which may well in fact
be what you want)
2) Bob has give you a solution that will count every instance of the number 1 in the cells in your
range. 11 would be counted as 2 lots of 1, 111 would be counted as 3, 101214171 would be counted
as 5 instances.
Your call, but just be sure you really get what you want.
