That code has some format errors in it. There was a bit of confusion on the IDE v1.0 Ethernet.begin() format. The client sketch code here downloads Google home page every 10 seconds.
Don't do that to Google too long, only as a test. Then change to your server ip.
This is server sketch code. It will convert two form inputs to integers, then sends them over the serial monitor.
edit: I had to find my a link to the server code. No sense posting it twice.
