Sadly all examples are written in Javascript, so there is no
possibility to modify running code slowly.
1. Can somebody tell me how to better find out where problems in my
code is? Perhaps some debugging messages one can print out?
2. Can somebody check my code below and tell me what to change so it
works? Or provide me with a similar example using JSon?
Cheers,
