I am trying to use a lookup-function to determine a different sum
range for several criteria.
Like so:
=Sumif($A$7:$A$1447;"<"&X3;vlookup(e3;AT3:AU11;2;f alse)-Sumif($A$7:$A
$1447;"<"&y3;vlookup(e3;AT3:AU11;2;false)
The problem is that the vlookup returns text and not the cell
reference. Is there a way to get the answer from the lookup expressed
as cell reference instead of text, since sumif can't use text, just
the cell reference?

I use it to calculate the number of hours the staff should be paid,
so
it's different from weekdays to saturdays, holidays and sundays
in at3 to at11 i have the days (1 for sunday) of the week and in au3
to au11 i have the ranges for the reference table with pay per
minute.
