How about, recording a macro.

Have say cell A1 as what the old file is
and cell A2 the new one.

Then record a macro that would pick up A1 and replace with A2.

then you'd just have to change A1 and A2 ecah day and run the macro.

Might work.

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.
