It sounds to me that you are trying to emulate the NETWORKDAYS Analysis
Toolpak function, which calculates days between two dates, and can ignore
holidays.

I have a sheet that has 5 columns
(DayName,CalendarDay,Impact,Holiday,Result). The basic idea is that it has
every day in the year listed (and actually goes out to the beginning of
2008). The Impact column is what holds the modifier for dates. If there is
a
holiday then we have to add a Plus/Minus modifier in this column which
tells
the formula to add or subtract days for cutoffs on delivery or receiving.
Now
what I am trying to do (from a module not formula because formulas get to
messy in large spreadsheets) is write a function that does a lookup on
this
page and returns the Impact for that day of the year. However, when I run
my
code I get NOTHING, ZIP, not even a ZERO back. I put error code in to see
if
the code was getting an error and nothing.

Also if anyone has a better example for the data section I am ready to
hear
it. At this point I figure to cut the page data down by removing days that
have 0 Impact. I have inherited this spreadsheet and I am trying to update
it
to work better. We have several people who use versions of this
spreadsheet
and make mistakes on it because they do not understand the formulas, so I
am
putting all that I can into modules.
