Compare Fields in Subform then format

[Bill Phillips]

I have a physical inventory application. In the form there is an ItemID which
is linked to the subform via ItemId.

The subform can have 1 or more records representing a single location. On
each of these records there can be multiple counts because sometimes people
don't count the same quantities. I want to compare all the counts from a
single location and see if I have 2 that match. How can I accomplish this?
the counts are all entered in in a batch # number consecutively from 0 to 20.
I may have just 1 count or up to 20, and it will vary.

Sample Data:
Item A
Location A has counts of 1,3,4,7, 3
Location B has counts of 6,12,6

I would like to change formatting for Location A both counts = 3 and do the
same for location B for both counts of 6. I think I know how to do the
formatting, I can't quite get how to evaluate the fields. I don't know if I
need to evaluate the value of the controls or what.

thanks for any assistance. Using Access 2003.

You may need to more rigorously specify your requirements. For example
what should happen if LocationA has counts 1,1,1,2,2,2,3,3,3,3,4
IOW, do you want to highlight ALL counts with >= 2 matches, or the
largest one, or ...
To count in SQL you could use something like:
select ItemID, count(*) from myTable
group by ItemID
having count(*) >= 2

How is the inventory data stored for a location? Post table structure with
field names and datatype. Post sample data from the table.
