Thanks!! This did not work, I don't think I explained it right. I have
a
workbook with 2 worksheets. Worksheet #1 is "weekly production" and is
set
up
by the week starting on every sunday. Worksheet #2 is "daily
production".
What I am currently doing is entering the daily production in and then
calculate how much was done for the week and enter the totals into the
weekly
spreadsheet. What I want to do is enter the data in the "daily
production"
worksheet and then have a formula in the "weekly Production" worksheet
that
will link it from the daily over to the weekly and add it on its own.
On
the
daily production and weekly sheet the dates start in a3 and then the #
of
product sorted starts in c3 on the weekly sheet and b3 on the daily
sheet.
Please help!!

I am trying to add how much production was done at our facility per
week. I
have 2 worksheets one for a weekly total and one for daily
production.
I
want
to enter the data in the daily spreadsheet and then have a formula
add
the
production numbers based on the dates that fall in that work week.
October 1st is the first so I do not need a greater than and less
than
formula for that one only a greater than 10-5-08 formula. For week 1
in
October I tried =sumif('Daily Production'!A3:367,"<A3",'Daily
Production'!B3:B376) but it comes back zero. I also need to know how
to
get
the numbers for week 10-5-08 thru 10-11-08 11 and so on for the rest
of
the
year.

This is what my spreadsheets look like:
