Your method tells me how many times each combination appears. I must have
asked the question in the wrong way.

Hi,

Put this formula in g1 and drag down

=D1&E1&F1

Put this formula in H1 and drag down

=COUNTIF($G$1:$G$20,G1)

The second formula will return a 1 for unique items so filter by 1 on column
G and you have a unique list.

E &F?

Thanks in advance for sharing your expertise.
