Column A is total time in seconds
Column B is A/60 - for minutes
Column C is B/60 - for minutes/seconds ??
In Column D, I'm running the total with these formulas =SUM($K$6:K12)
($K$6:K13), etc., in the D column.
This particular formula =SUM($K$6:K12)
is in the 0:04 <------ cell below
The running time seems to work for the most part (1:46, 2:41, 4:57, etc.),
but when it gets past the 17:40 time, it produces 0:04 instead of 24:04. The
same thing further down with the <---- 6:27.

I'm sure it's something do do with the 24 that I don't have right. Any help
would be greatly appreciated.

Thanks,

Steve
