Location on the page: 
First code sample
Error: 


if (!isset($name)) {
$name = t('good looking!');
}

Correction: 


if (!isset($name)) {
$name = t('good looking');
}

Description of the Error: 

When $name is emitted later in the code, an exclamation is added there, so it's not needed in $name. This is corrected in the second code sample on the page.
