Imelda,

Have you tried simply summing the values:

=SUM(L4:L70)

and using the custom format

[h]:mm

or

[m]:ss

(depends on how those values are actually entered....)

I'm trying to add the following list of times:
09:30 + 09:00 + 09:00 + 04:00 + 08:30 + 08:30 + 06:00 + 05:00 + 05:00 +
07:00 + 08:00 + 05:00 + 04:00 + 07:30

Using the following formula:
=IF(INT(ROUND(SUM(L4:L70)/0.04166667,2)) = 0, "",
INT(ROUND(SUM(L4:L70)/0.04166667,2)) &":" &
IF(MINUTE(MOD(SUM(L4:L70),1)) < 10, "0" & MINUTE(MOD(SUM(L4:L70),1)),
MINUTE(MOD(SUM(L4:L70),1))))

The problem lies in the part of the function marked in bold. This
function is working perfectly with all/most other combinations of
times.

Hopefully someone can help me.

Thanks,
Imelda.
