I am trying to make the following formula change based on values
(text) in other cells:
='M:\RAPP\[ATL08.xls]200803'!$G99

In Cell A1 I have ATL, and in cell A2 I have 200803. When I change in
cell A1 to TOL and cell A2 to 200804, I want the formula to be:
='M:\RAPP\[TOL08.xls]200804'!$G99

Tried: ='M:\RAPP\[&A1&08.xls]&A2&'!$G99 but does not work. Also can
not get Indirect to work, and even if I did, would like to find
something that does not require the external workbook to be open.

Anyone have ideas?

Brgds,
Harald
