I think you'll need the INDIRECT() function.

I want to add the sum of cell D20 in all worksheets from the first up to
the
current. I have tried:

=SUM(Sheet1:MID(CELL("filename",B2),FIND("]",CELL("filename",B2))+1,256)!D20)

but I get an error.

Putting =MID(CELL("filename",B2),FIND("]",CELL("filename",B2))+1,256) into
a
separate cell returns the current workspace name, but it doesn't work in
the
formula.

Any of you experts have any ideas?
