There are 2 macros below:
The first one defines a user's workbook name (we will not know that) and
jockeys back and forth with a workbook in which we do know the name. THe
problem arises when the first macro calls the second macro. THe second macro
resides in the known named workbook and it needs to jockey back and forth
with the 1st workbook. The problem is the second macro does not recognize
the variable name that represents the first workbook. I know this sounds
confusing. I hope the code below explains some of the problem:
Real question is, How can we refer to the 1st worksheet when we won't know
the name. We do paste its name into a cell in the 2nd file. Can we somehow
use that cell data to refer to the 1st workbook?

Thanks so much.
