=INDIRECT(A1&"!A1")
Note that you do not need the single quotes around the sheet name when it
contains no spaces
If your value in A1 is something like Year 2009 (ie the sheet name has a
space in it)
=INDIRECT("'"&A1&"'!A1")
That is:
INDIRECT( double-quote single-quote double-quote &A1& double-quote single
quote !A1 double-quote )

Good morning,

On my summary worksheet Cells A1:A50 are the names of the 50 other
worksheets.

I wish to insert Cell A1 of the repsective worksheets adjacent to the tab
names in Column B, e.g.

Cell A1 Sheet1
Cell B1 ='Sheet1'!A1

How would I change this formula to refer to column A on my Summary
worksheet?


Kind regards,

Neil
