Multiple snapshots on the same database.

I'd like to create multiple "replication" on the same database in order
to sync only some tables in each replication. When I try to add a
second push replication to the subscriber i got the following error:
"The subscription already exists."
Is there a way to do this?
Christian - do you have multiple publications? It sounds as though you are
setting up multiple subscriptions but to the same publication, judging by
the error message.
