8 411 3 0:44:03 1:17:27 2
9 409 2 0:38:38

I am try ing to determine some code so that as the lap time turns up in
column k the riders place automatiucally turns up in column L. The place is
equal to the number of times in column k.

Thanks

basically what i want is when any cell in the range k5:k9 changes the value
of max(l5:l9)+1 goes in the adjacent cell in column l
