Although the suggestion off Bob works like a charm, which I thank him for.
I am still interested how it could be done with pivot table.
As a newbie, I had a look at it and it seems a nice feature.
Yet I cannot find the right placement to view the correct result in a pivot
table.
Can someone give me some more explanation on how to do this or is a pivot
table not useable with only my 2 column data.
Thx in advance,
