Working with columns of data

I have a spreadsheet with two columns of data. The first column contains an
8 digit number to identify each factory. The first 6 digits represent the
main factory and the remaining 2 represent the feeder plants for the factory.

The second column contains text that identfies if the factory(s) are "Open"
or "Closed".

The goal is to automate a way to determine if a factory and all it's feeder
plants have closed. Since a factory can have a dozen feeder plants, my
spreadsheet contains over 3000 rows.

How would I write VBA code to loop thru the columns to determine if all
factory/plant combinations are closed?

Hi,
Assuming data goes from row 1 to row 3000
in column C, enter:
=SUMPRODUCT((LEFT(A1,6)=LEFT($A$1:$A$3000,6))*($B$1:$B$3000="OPEN")*1)
This will return the number of open feeders. (a bit repetitives since it
will be on each row)
Just filter for the zeroes to get factories with no open feeders.
