I am to create a formula which sums the best (highest) 8 numeric values.
Values are stored in rows as follows (Columns A to L) and in many rows

12 43 54 23 12 34 54 56 76 87 98 12
43 45 43 45 67 86 43 32 12 34 54 56

Column M should then show the total of the highest 8 values. Is there a way
to do it?
