Newbie here... getting a count of repeated instances in a list.

[Amy G]

Okay.  You rock Peter!!!  If I can just enlist your help a little more...

I now have two dictionaries, each with domains and frequncies.  I want to
have the domains which appear in both to be deleted from the first one.

Is there an easy way to do this?
