wow, that was just what i was looking for, thanks alot
iv tested it alittle now, and from what i can see, it had a few small "errors"
it looks like the "Night" calculations are working great so far. the only thing iv noticed there is that if "Start" and Finish" are left empty, it shows 6 hours in the "Night" section.
it would be great if it is left empty, or as 0 so i can add a automatic sum for amount of "Night" hours to it when its done.
on the "Weekend" part, it seemed to work on not counting monday to saturday 18:00, but when on saturday, no matter what time i enter as start time, it counts how many hours from 18:00 to "Finish" time. (if i enter 20:00 - 21:00, it still counts from 18:00 - 21:00)
and if "Start" and "Finish" are empty, "Weekend" shows #'s, but this is only on the line with Saturday.
also, if "Finished" does not have a time of 18:00 or higher, it also shows #'s on "Weekend" for Saturday.
on sunday, it looks like the "Weekend" does not end at 06:00 monday, it just keeps counting all the hours.

i have tried to do alittle fixing on this myself, but it seems it is alittle over my head atm to do by myself
