未定义索引：具有$GLOBAL变量的类型

问：

我设置了一个超级全局变量，但在另一个文件中，在运行程序时无法访问该变量。$GLOBALS['Type']="JobSeeker"Undefined Index:Type

第1页.php：

$con = mysqli_connect("localhost","root","","job1");
// Specify the query to execute
$sql = "select * from JobSeeker_registration where JobSeekerId='".$ID."'  ";
// Execute query
$result = mysqli_query($con,$sql);
// Loop through each records 
$row = mysqli_fetch_array($result);


$GLOBALS['Name']=$row['JobSeekerName'];

$GLOBALS['Email']=$row['Email'];

$GLOBALS['Approval']="Confirm";

$GLOBALS['Type']="JobSeeker";
.
.
.
.
include '../Mailing/MailSending.php';

邮件发送.php：

if($GLOBALS['Type']=="JobSeeker")  //Here is Error:-Undefined Index of Type
{
    if($GLOBALS['Approval']=="Pending")
    {
        $UserName=$GLOBALS['Email'];
        $mail->addAddress($UserName, $GLOBALS['Name']);
        $mail->Subject = 'Registration Mail';
        $mail->msgHTML(file_get_contents("Mailing/Pending.html"), __DIR__);
        $GLOBALS['Email']="";
        $GLOBALS['Type']="";
        $GLOBALS['Name']="";
        $GLOBALS['Approval']="";
    }
    elseif ($GLOBALS['Approval']=="Confirm") 
    {
        $UserName=$GLOBALS['Email'];
        $mail->addAddress($UserName, $GLOBALS['Name']);
        $mail->Subject = 'Registration Confirmation Mail';
        $mail->msgHTML(file_get_contents("Mailing/Confirm.html"), __DIR__);
        $GLOBALS['Email']="";
        $GLOBALS['Type']="";
        $GLOBALS['Name']="";
        $GLOBALS['Approval']="";
    }
}

我尝试使用不同的名字，但没有得到任何解决方案。
