This formula gives me an invalid cell reference. Does the
other workbook
have to be open?

The course you'll have to follow then is this:

change your formula
='V:\Production Reporting Summaries\Tammy\April 05\[Production
Summary.xls]4_04'!$B$4

to
=SUMPRODUCT(INDIRECT("'V:\Production Reporting
Summaries\Tammy\April
05\[Production Summary.xls]"&A1&"'!$B$4"))

and then put your 4_04 value in cell A1

This is a formula I us daily

(example)
='V:\Production Reporting Summaries\Tammy\April
05\[Production
Summary.xls]4_04'!$B$4

each day I have to make a copy the previous days
worksheet and then go into
multiply cells and change 4_04 to the next day, which
would be 4_05.

I want to be able to enter 4_05 into one cell and have
it update 4_04
automatically so I am not manually changing the formula
daily.
