I think I've left the hardest question to last. See data below

I need to sort the riders to determine places. The H,I.... and 5,6... are
cell references (and do not change) if that helps. The number of laps any one
rider may have completed in a race varies from 0 to unlimited. Riders are
ranked by number of laps completed and then finish time on their last lap if
number of laps is equal.

There are 2 ways to determine the number of rows for sorting that I can see.
1) determine the number of rider names till the first blank
2) just sort every rider number anyway even if unused. The maximum rider
number is 199 (row 104).

My hassle is determining the max number of columns for the range and then
sorting the rows based on what could realistically be 30 columns of times.

Thanks
