We have a WINNER!! Thanks very much. That works as expected, the only
slight problem it may cause is for example: If I select 8no 3's, 1no 2's
and 3no 1's. The calculation has added them all up to get 29 then
divided by 12 to get 2.4 and so doesn't round up. However when you look
at the sheet there are more three's than any other score so having the
average score as 2 appears to be wrong, even though the calculation is
correct. I'm not sure how the user wants it to appear so this may be
fine but...
