Hi David
please read my last respsonce to Jacob,

what i am trying to do is set out a spread sheet that enables my wife to
enter a start time, an end time, with the total hours against each day and
then to add up the total hours for that week at the end of each row for her
staff. but if they work over 7 hours per shift then 0.5 hr will have to be
deducted
eg 10:00 start time and 22:00 end time = total of 11hrs .30mins
if they worked 08:00 to 12:00 then it would be a straight 4:00hrs as there
is no deduction.

What seems to be happening ref to the totalling is that when it gets to
over the 24Hrs total it the carries on to count like a clock would.
eg a total that should read 24hrs:30min in showing the total being 00:30


please any asstance would be grateful

Firstly, could you please explain to us what you want the SUM function to do
in =SUM(C1+F1+I1) ?
Why not just =C1+F1+I1 ? What do you want to sum with C1+F1+I1 ?

Secondly, you say "does not come up with this total" but you haven't told us
what total you have come up with, so it's rather difficult for us to tell
what you've done wrong.

Thirdly, in another reply to Jacob's message you said "i had to set the cell
format to "Time""
What was wrong with Jacob's suggestion of:
Custom format C1 to [h]:mm ?
You will see that his suggestion copes with values beyond 24 hours when you
add them up, but yours doesn't.

Hi again its me sorry

That works great, but when i am trying to add all the totals together at
the
end coulb say "J" it does not work as it comes up with just adding the
time,
in stead of
10:00hrs to 22:00hrs equals 11:30 for Monday (less the .5 hr), for Tuesday
it is 08:00hrs to 12:00hrs equals 4.0hrs (do not subtract the 0.5 hr as
it
is less than 7 hrs total), Wednesday 08:00hrs to 12:00hrs equals 4.0hrs
there for the total for the week should read in say columb "J" total 19.5
hrs
for that week
formula used =SUM(C1+F1+I1) but it does not come up with this total?

sorry to be a pain

Entering 10:00 to A1 will automatically custom format cell A1 to h:mm
Entering 22:00 to B1 will automatically custom format cell B1 to h:mm

Custom format C1 to [h]:mm and try the below formula

=IF(B1-A1TIMEVALUE("07:00"),B1-A1-TIMEVALUE("00:30"),B1-A1)

Hi Again
Just had a look over the formula you have suggested to try, if there an
issues with the "07:00" value as this is a time value and not a total
between
the times

eg 08:00hrs to 13:00 hrs equals a Total of 5 hrs
threrefore 07:00 is a time value and would generate a zero??

A1 = 10:00
B1 = 22:00

In C1 try the below formula

=IF(B1-A1TIMEVALUE("07:00"),B1-A1-TIMEVALUE("00:30"),B1-A1)

Hi I an trying to generate a formula to enable my wife to calculate
the off
duty for her section.
i have used 3 cells to start off with just to see if i could get it
to work,
cell 1 = start time, Cell 2 = end time, Cell 3 = total.
e.g. start time =08.00, end time =13:00, then total time = 5hrs,
formula say
=sum(d3-d2) simple. Ok
Well this is the part were i have got stuck. If the total is equal
or more
than 7 hours then i need to subtract 0.5hr, but only if it is equal
or
greater
so say start time is 10:00, end time is 22:00 then is should = 11.5
and not
12 hrs as the sum is greater than 7hrs
Can some kind person out there help with the formula

cheers
