Thanks for any help you may be able to provide.

Yesterday there was a post about counting unique values.

The reply had a link to a frequency formula -

The OP never replied back so it's unknown if that formula
worked.

I'm always interested in learning new techniques so I
played around with this formula.

The problem is this formula doesn't work. I copied the
formula to a worksheet (had to remove some junk that got
embedded from the Google archives) but when I tried it I
got an error message that said "not enough arguments for
this function".

The formula doesn't include the Bins_Array argument for
the Frequency function. So I added that argument as an
empty range -

Z1:Z5 with nothing in that range.

According to Excel help, If bins_array contains no values,
FREQUENCY returns the number of elements in data_array.

Well, that did not work. I kept getting results of 0.

Can anyone help me understand that formula and how it
works?

Thank you
