Thanks Alan and vletm. The range is not fixed (no. of rows may increase/decrease) and the data gets updated on a frequent basis. That's why looking for a dynamic option for this.

Dynamic option ... hmm?
With my sample solution no matter of number of rows.
You can add or delete as many row as You have time.
... or ... there should be those Your used 'key rows'.
How dynamic option would You like to have?
Could You explain it eg with 50 words?
