I may be way off base, but I'm having the impression that you may need to spell
out each filter for each datasource.
I tried a separate action filter for Manufacturer going to EuroCustomers,
a separate action filter for Manufacturer going to AmerCustomers,
and a separate highlight action going from ManuEur to ManuAmer.
Please see workbook v10.2 attached in the Forum Thread.
