Hi Farai. Whenever your challenge fails, you get a message at the top. Here it says: "Bummer: There is a compiler error. Please click on preview to view your syntax errors!"

If you click on Preview, you will see the following:

./FunFactsActivity.java:16: error: cannot find symbol
        Button showFactButton = (Button)  findViewById(R.id.shawFactButton);
                                                                                                 ^
  symbol:   variable shawFactButton
  location: class id
1 error

So it tells you the problem is that it cannot find symbol, then further down it indicates what symbol it cannot find: symbol: variable shawFactButton

Looking at it carefully, you will notice that you have a small typo: it should be showFactButton, not shawFactButton.

Correct this and you'll be good to go. Hope that helps :)
