Twitch Procedual Content Training (Room creation) Problem

[blendcry_1 (AnsgarSchwarzer)]

Hello there,
These days I wanted to follow the Twitch Training about Procedual Room Creation, but got stuck after a few minutes.
Actually this is supposed to be a square… Can anybody tell me were I could be wrong in the Graph?
