No bug here: you're outputting text containing a '<' to a web page,
so the browser will try to interpret it as the start of a tag if it's
immediately followed by a character. In your profile class, change
$this->age_Range = $age;
to
$this->age_Range = htmlspecialchars($age);
and you'll see what I mean. (You could always just use 'View source',
I s'pose).
