I'm sorry i forgot the details. it simply didnt react to a click at all, which probably was because i didnt link it to an event like you mentioned.
I actually (more by accident while fooling around) tried the event button. since then I can enter room 2 from room 1, but once i try entering room 3 or 1 i get this error:
I tried to delete the hToilet Script, (No changes made on the hAusgang Script) but i still get the error
I guess i should start over, Thank You for your answer and the Tips, If i ever solve this I'll update you
edit: I deleted the room2 script and startet over, I got the "It runs!" message but i still get -> Error -18 (No such Function in Script)
