I don't understand this answer. I have a column of times, summing to zero.
I have tried the formula, SUM(G2:G10)*24, formatting the cell [h]:mm, both
found in the help menu. I have tried the formula with the + operator as
suggested here. Nothing works.

The times being summed are a result of IF(F2="","",TEXT(F2-E2,"[h]:mm")), I
have also taken the bracets off the h, but then loose + 24hour periods. What
does add radio buttons do?

SUM() ignores text, while the + operator will coerce its text arguments
to numeric if it can.

Try coercing your data to actual numeric values (which is how XL stores
times - as fractional days) by copying an empty cell, selecting your
values, choosing Edit/Paste Special, selecting the Values and Add radio
buttons, then clicking OK. Format the result as time.

Is there anyone out there who knows why the SUM function won't work, but
manual addition will?
