Linking docs
 

I have linked 3 excel docs which have about 90% similar formatting and
formulas. in these docs i have a list of questions which differ slightly and
I would like to have columns with similar question to input in all three
excel docs. e.g question 1 in all three docs is the same, question 2 is
different across them. if answer in question 1 doc 1 is genius to have an
automatic input in doc 2 and doc 3.

Any suggestions on this (please note that these columns have an existing
formula),

thanx
