Hi Thomas. Did you declare your 2 variables at the top of the class (under the class name)?

private TextView factTextView;
private Button showFactButton;

If you have, then just paste your code here so we can help you further. Thanks :)

Also, if the red text is for the R.id.factTextView part make sure the id in the layout file is spelled correctly and that there are no errors in the XML.
