Blank Emails php - php

Question

some emails are coming up blank in my inbox. I think the reason may be here in the source code.
The left image is the one that presents the error.
Code:
define( 'OWNER_EMAIL', 'leads#consorciomenegalli.com.br' );
define( 'DONOTREPLY_EMAIL', 'do-not-reply#consorciomenegalli.com.br' );
define( 'OWNER_NAME', 'Menegalli' );
case 'quote-form':
# put the email title here
$title = 'Nova simulação via website';
# email headers
$headers = "MIME-Version: 1.0\n".
"Content-type: text/html; charset=utf-8\n".
"Content-Transfer-Encoding: 8bit\n".
"From: ". $_POST['clientName'] ." <". $_POST['clientEmail'] .">\n".
"Reply-to: ". $_POST['clientName'] ." <". $_POST['clientEmail'] .">\n".
"Date: ". date( "r" ). "\n";
# appointment values
$values = $_POST['values'];
# create rows with values from appointment form
$rows = '';
for( $i = 0; $i < count( $values ); $i++ ) {
$rows .= '<tr>
<td style="width: 200px; font-weight: bold; border: 1px solid #eee; padding: 10px;">'. $values[$i]['name'] .'</td>
<td style="border: 1px solid #eee; padding: 10px;">'. $values[$i]['value'] .'</td>
</tr>';
}
# email content
$content = '<table style="width: 600px; font-size: 11px; border-collapse: collapse;">'. $rows .'</table>';
# sending an email
$result = mail(
OWNER_EMAIL,
"=?UTF-8?B?". base64_encode( $title ) ."?=",
$content,
$headers
);
# if the email wasn't send
if( $result == false ) {
# second version of email
mail(
OWNER_EMAIL,
"=?UTF-8?B?". base64_encode( EMAIL_TITLE ) ."?=",
$content
);
}
break;
I think the email is not picking up . $values[$i]['name'] . and . $values[$i]['value'] .
