Formula Question
 

How do you automatically calculate information in unhidden cells that contain
a formula to calculate from another spreadsheet that shows data and hidden
cells that have a formula to calculate from another spreadsheet that returns
a Div/0! because data is unavailable without the formula result being Div/0!
because the hidden cells do not contain any data?

Formula Question
 

It's probably best to suppress the errors in the first place. If you
have a formula like

=A1/B1 which gives a #DIV/0! error then you can change to

=IF(B1,A1/B1,"")

alternatively you can sum a range, say C1:C10, and ignore #DIV/0!
errors with

=SUMIF(C1:C10,"<#DIV/0!")
