You don't need both of them on at a time. One or the other.
For VCE after you have it so it gives you logs for chopping it, to check it basically just make something like
OnActivate>Client>ChatMsg>You have <var:pl:Logs> logs!
You can substitute the "pl" with player, cl or client. And make sure you have the "Logs" after pl the same way you have it for when you make the tree give them logs.
IE if the tree gives you one "log" but the event to view your logs "Log" it would not work.
