I have two worksheets: Report and Weekly Report. On the report I have the
data listed by days. Some days are five day work weeks and some can be up to
seven day work weeks.

Simple example below
Report
Date Failures
12/3 5
12/4 6
12/5 3
12/6 9
12/7 10
12/10 3
12/12 2
12/15 1

I want the weekly report to look like this:
Week Of Failures
12/3 33
12/10 6

I want to use macros for these examples.

Thanks

Sounds like homework. Have you looked in the help index for WEEKNUM

If dates in K and failures in L then enter 12/1/2007 date in cell o1. The
next formula in o2
$O$1-WEEKDAY($O$1,3)+ROW(A1)*7
and copy down as desired. Then in p2
=SUM(IF(($K$2:$K$22=O2)*($K$2:$K$22<=O2+6),$L$2:$ L$22))
adjust number of rows to suitARRAY enter using ctrl+shift+enter. Then copy
down to match col o
