Bartik No Title Pages

Simply put, I need certain pages on my website without node titles. There were a few suggestions that I tried to follow and it worked, except for one thing.

This is what I did:
1. I created a new content type and called it “notitle”. The machine readable name for it is also called “notitle”.
2. I then created a new node in this content type just to test it.
3. I opened the page.tpl.php file and did the following I changed the lines from:

      <?php if ($title): ?>
        <h1 class="title" id="page-title">
          <?php print $title; ?>
        </h1>
      <?php endif; ?>

To this:

<?php /*?>This below checks for 'notitle' content type and then it doesn't print the title,
          however it still prints the normal title for page content type<?php */?>
      <?php if ($title && $node->type != 'notitle'): ?>
        <h1 class="title" id="page-title">
          <?php print $title; ?>			  
        </h1>
      <?php endif; ?>

All of this worked great and it then didn’t display the title anymore for the “notitle” content type’s nodes, however…

4. When I log in as administrator I get the following error message:

* Notice: Undefined variable: node in include() (line 191 of C:\wamp\www\themes\bartik\templates\page.tpl.php).
* Notice: Trying to get property of non-object in include() (line 191 of C:\wamp\www\themes\bartik\templates\page.tpl.php).

The code for line 191 is the following:

      <?php if ($title && $node->type != 'notitle'): ?>

5. Do you have any suggestions please? I’m not very good with php, but certainly try my best. Any help would be great.

Thanks in advance.
