"Cursor already exists" error

We need to get a script done for our client (their developers, DBAs in the dept quit within a few weeks and no one bothered to ask them to turn over their code and scripts!)

My manager came up with this cursor loop but I get an error (I know cursors are not recommended but we have to get this done for now). Not sure where he got the script but I think the placement of closing the cursors is off somewhere..

error: A cursor with the name 'activationCursor' already exists.
