Thanks,
it works (after I found the german translation - english doesn't work with
this 2003 any more), but it is still not useful for endusers.
I use now f.e.

A1 = input cell, format [h]:mm
A2 = empty
A3 = A2-A1
A3 cell format is [h]:mm

but it is not very nice for using, because you cannot use one cell for + and
- values as the user just likes to put in the needed hours.
But it is possible, to use as a workaround.
Regards
Michael

=-(INT(50/24)+TIME(50,0,0))
or
=-INT(50/24)-TIME(50,0,0)

works ok for me.

But it's pretty ugly!

hi there,
i can calculate and, since i use the 1904 format for it, also with negative
values.
but still it is not possible to give an input of f.e. -50:00:00 means minus
50 hrs.
any solution for it?

michael
