Maybe something like this:

=SUM(OFFSET(A28,1,MATCH("L1",28:28,0)-1,n))

Where n = the number of rows to include in the sum.

Row 28 is workcenter names (L1, L2, B1)
Rows 29 through 105 are production cases for each workcenter by calendar
day
I want to lookup L1 in row 28 and the sum the first 7 rows under L1 so i
get
a total # produced for L1 for the first 7 days. Then i want the first 14
days, then 28 days.
I am not having any luck getting anything to work. Workcenter may not be
in
the same column every time and the dates will always change depending on
the
time frame i use.
L1 L2 B1
