I inserted my network information in this code which was written by arduino.cc

but it doesnt work.. is there anyone who can help me out? T.T;;

Which parts work and which don't ?
What exactly happens when you run the program ?

No. That code was written by me and posted in the playground.

UKHeliBob asked the correct questions.
