Hi folks.
Really need a hand with this issue:
I need to highlight top values (in a seri that sum up to 80% of the total value (if the sums goes under 80%, it should also highlight the next top value)
For instance:

Value:
35%
2%
4%
5%
6%
7%
18%
23%

So in this case I should highlight the following numbers: 35%; 23%; 18%; 7% (equal 83%)

Any clue on how formatting this??

HELP please
