You need to add an "else" statement to your code with the reverse message. 

} else { alert("a is not greater than b");
}

else is a keyword that covers all other conditions so you don't need to test for any other conditions specifically. :-)

Good luck!

Edited to add the alert method to the else statement for completeness. My apologies :)
