Simpel cookie - skriv navn på besøgende + antal besøg

Jeg har oprettet 2 sider - en velkomstside med en form, hvor brugeren kan indtaste navn. Siden har et script der skal danne en cookie med antal besøg og dette navn. I samme script er der en redirector - der sender \"gen\"besøgende til en anden velkomstside, hvor navn og antal besøg udskives - dette fungerer, men ikke optimalt.

Problem - det udskives således: \"Hello Philip Jerving. undefined Since this is the first time you have been here, please take a moment to look around.undefined\"

Hvor ligger fejlen siden der udskives \"udefined\" både efter navn og antal?

KODEN SER SÅLEDES UD:
