You can use indirect

=INDIRECT(A1&"!$D$20")

And copy down

I have a summary tab that is lad out as follows:
Column A Column B
1101
1102
1103

I have individual tabs named 1101, 1102, 1103, etc... This is one field in
each tab (same cell reference D20) that I want to link in the summary. I
know I can click on each tab and do a simple link =+'1001'!D20 - but
wanted
another way - more effecient way using a formula in the summary tab- a
look
up of sorts. Any ideas??
