Hello

I would like to use the contents of cell A16 as my sheet sheet reference and
the current row,colum as the cell.
A16=Sheet1
then formula in b16 would return 'Sheet1!B16
I have tried (ADDRESS(ROW(),COLUMN(),1,FALSE,A16))
but it returns "Sheet1!R16C2" not the actual value in that cell.
What am I doing wrong?
Thanks!
