I have one master workbook and several sub-workbooks. All the sub-workbooks
get assumptions from the master workbook and return the result to master
workbook. Is there a way to automatically update all the sub-workbooks after
I change some assumptions in the master workbook and return the new result to
master workbook?

I've tried Edit/Link/Update now in the master workbook after I changed the
assumptions, it doesn't work.

Any help will be greatly appreciated.
