Hi, I'm trying to create a VLOOKUP using INDIRECT to point the vlookup to the target file, but I'm having trouble with the syntax in the cell I'm referencing with the INDIRECT. - At least I think that's the problem!

The VLOOKUP I'm using is: 
=VLOOKUP(Contacts!B3,INDIRECT(D8),2,0)
, and the data in cell D8 is 
'T:\NTGI Middle Office\Client Reporting\ADIC\Monthly Reports\ADIC1\September\[ADIC1_Perf.xls]USD Historical'!$A:$E
Currently I'm getting #REF! as a result of the above.

Is anybody able to help?
Many thanks,
