Calculate Time

[Tamara]

If this function works: =TEXT(F9-E9, "hh:mm:ss"), why doesn't this:
=TEXT(H2:H9, "hh:mm:ss")? I have a form enter start and end times. In
another column I use the first function above to calculate the elapsed
time. I would like to total that column in hh:mm:ss format. How do I
do this?

Because you have a "-" in the first place and a ":" in the second?

Hi Tamara,

=TEXT( XXX , "hh:mm:ss") is only a way to show differently XXX.
In first case, XXX is a difference. In second, H2:H9 is a group of
cells. But what Excel needs to do with this group to give a result ?

You indicated to search for a total :
Does =TEXT(sum(H2:H9), "hh:mm:ss") answer your wish ?

you already recevied an answer on how to do it. However,

With your current formulas you could do

=TEXT(SUMPRODUCT(1*H2:H9),"[hh]:mm:ss")

Hi
you are probably looking for
=TEXT(SUM(H2:H9), "[hh]:mm:ss")

But why use the text function at all?
simply use
=SUM(H2:H9)
and goto 'Format - cells' and use the custom format
[hh]:mm:ss

Reason: With the latter one you can use the result for further
calculations. If you use TEXT you first have to convert the string to a
numeric value before you could use it for further calculations!

since she used Text function to produce the results in H2:H9, using a
straight sum function will only return zero. I showed how to use sumproduct
to convert them to summable values.
