Your arduino is not accepting the sketch. There are a whole bunch of reasons but you provided zero details of what you did. This is like posting on a "medicine" website saying "I'm sick. What drug should I take?". Now get to work on the following if you hope to get any sort of help.
- Post your code. Don't say "I used exactly the code from ..."
- Post LCD spec sheet
- Post high-res pictures of how you connected your circuits, no fuzzy pictures. We need to see all details.
