How do I use an indirect reference to a sheet in another workbook?

[Guest]

I am working with a formula which references a sheet in another workbook:

=SUM('Q:\ServCtr\ACCT\[ACCT Validation.xls]AL'!$D$290:$D$318)

This works, however the "AL" above refers to Alabama and I need to use this
formula for each state which has a separate page. I have a list of all state
abbreviations in my current workbook and would simply like to reference this
by cell instead of using a different state abbreviation on each line. I've
attempted many variations of the following formula (where B7 is the cell
which contains the abbreviation AL)...but no luck.

=SUM(INDIRECT('Q:\ServCtr\ACCT\[ACCT Validation.xls]"&B7&"'!$D$290:$D$318))

Any suggestions would be greatly appreciated! Thanks!

Using INDIRECT requires that this file be open otherwise it won't work.
Also, since the file MUST be open you don't need the full path:

=SUM(INDIRECT("'[ACCT Validation.xls]"&B7&"'!D290318"))

Most people are disappointed when they find out that the other file needs to
be open.
