Error while creating Word Document

[metomeya]

I got this error while trying to create a word document.

Fatal error: Uncaught exception 'com_exception' with message '<b>Source:</b> Microsoft Word<br/><b>Description:</b> The requested member of the collection does not exist.' in C:\xampplite\htdocs\print_short_list.php:25 Stack trace: #0 C:\xampplite\htdocs\print_short_list.php(25): unknown() #1 {main} thrown in C:\xampplite\htdocs\print_short_list.php on line 25

Line 25 is...

$word->Documents[0]->SaveAs($filename);

Here is the entire code

<?php

$word = new COM("word.application");

$word->Visible = 0;

$word->Documents->Add();

$word->Selection->PageSetup->LeftMargin = '2';
$word->Selection->PageSetup->RightMargin = '2';

$word->Selection->Font->Name = 'Arial';
$word->Selection->Font->Size = 10;

$word->Selection->TypeText("TEXT!");

// Save document
$filename = tempnam(sys_get_temp_dir(), "word");
$word->Documents[0]->SaveAs($filename);

$word->quit();
unset($word);

header("Content-type: application/vnd.ms-word");
header("Content-Disposition: attachment;Filename=document_name.doc");

readfile($filename);
unlink($filename);

?>
