Hi there!
Thanks so much
I used =SUM(IF(ISNA(MATCH(B5:F5,$B$3:$F$3,0)),0,1)) and it works :-)
It is a big help, but I think it can be improved.

This formula looks if the data is in one of the cells in the row is the same in another row.
But it should be delimited to columns search:
Sometimes the same specifications re-occur but on another variable. Eg "red color" is used for the tissue
sometimes for the buttons. The formula above does not detect this.
So I think this formula should be delimited to one cell of row $B$3:$F$3 and then make the sum of
all cells in the row to get the most matching produced product.
Could you provide an example formula for this?

It would also be very convenient if the cells in the database get a color code for the ones which do not match the formula, then we can
see straight away were the difference is.
It is like conditional formatting but trough a formula.

Your help is already greatly appreciated.
