The following is a hardcoded formula in a worksheet, call it the
CurrentSheet..

='210208345'!FSPTX/'210208345'!CurrentValue

Where '210208345' is the name of a worksheet, and FSPTX and CurrentValue
are names defined in thgat worksheet.

I can get the same reult using

=INDIRECT("'210208345'!FSPTX")/INDIRECT("'210208345'!CurrentValue")

But I'd rather not have to hardcode the 210208345, and FSPTX, as they are
values in cells in the CurrentSheet.
Is the following "best'?

=INDIRECT("'"&D$2&"'!"&B3)/INDIRECT("'"&D$2&"'!CurrentValue")

So B3 would change to B4 in the cell below.
