Read the condition to yourself: "If myAge is greater than 9, or less than 14", and you'll see that any number will return TRUE, because every number is either less than 14 or greater than 9.

 

You likely meant to use "If myAge is greater than 9 AND less than 14", which would be:

elseif( $myAge > 9 && $myAge < 14 ), which will result in TRUE for 10, 11, 12, and 13.
