Hi there,

You've got this line back to front:

Button showFactButton = (showFactbutton) findviewById(;

To the right of the equals sign you want to type cast this to a Button type. So, put Button inside the first brackets. Then inside the second brackets comes the ID of the button which is Also, Capitalise View inside findViewById.

You end up with:

Button showFactButton = (Button) findViewById(;

Good luck!


thanks alot Steve.!!
