Simple Routplanner (distance calcutaltor) help needed

[jazzy]

Hi, I am relativley new to Javascript, and a friend of mine helped me start programming, and I would like to present this to my computers teacher at school, yet I have a bit of a hiccup. For some reason a problem keeps popping up. Here is the code, if anybody could help that would be great! (it is partialy in german, because i am in germany, but i dont think, that that should be a problem )
