Try something like this:

With
A1:A20 containing Dates (A1 holds the title)
B1:B20 containing Invoice Numbers (B1 holds the title)

Then
F1: Date
F2: 2/1/2007

G1: InvCount
G2:
=SUMPRODUCT((($B$2:$B$20<"")/COUNTIF($B$2:$B$20,$B$2:$B$20&""))*($A$2:$A$20=F2) )


Increment dates in Col_F
Copy G2 down as far as you need.

Does that help?

Sheet1

Column A Column B Column C
(Inv Date) (Invoice #) (Line #)
2/1/2007 200112 1
2/1/2007 200112 2
2/1/2007 200113 1
2/2/2007 200115 1

On sheet 2 I want to count the number of invoices for each date above but
not count each line item as one invoice.

Sheet 2

Column A Column B
(Date) (Count)

2/1/2007 2
2/2/2007 1

I have a spreadsheet that I track invoices by day. How do I count the
number
of invoices by each day of the month? Some of the invoices have multiple
line
items on them so I don't want to count those as individual invoices. I
only
want to count the invoices for a day and only count 1 of the multiple line
item invoices. This way it won't count each line item as an invoice for
that
day.

Column A has the invoice date and column B has the invoice number. I want
to
put this on a different worksheet and summarize it by day. I have a list
of
days on my summary worksheet in column A. So basically I'd want to match
the
date on my summary worksheet with the invoice date.

Any help would be greatly appreciated.

Thanks
