Perhaps should have read your question a little more closely

How about

=IF(SUMIF(City,"New York",TotalInv)=0,0,SUMIF(City,"New
York",Sold)/SUMIF(City,"New York",TotalInv))

Like a previous post, trying to avoid the #div/0 error. I tried to get
something from the previous post, but have no ideas? Any help?

Named Ranges:
City = B1:B1000
Sold = Total Number Sold, C1:C1000
TotalInv = Total Remaining in Stock, D1:D1000

=SUM(IF(City="New York",Sold,0))/SUM(IF(City="New York",TotalInv,0))
