Put this code inside page?

Hello,

Is it possible to put a guestbook code inside a post/page and make it show that way.

The reason I want to do this is so I can use it in tabbed content.

I tried this code inside the page but it doesnt work:

<?php if ( function_exists(‘vgb_GetGuestbook1’) ) : ?>
<?php echo vgb_GetGuestbook1(); ?>
<?php else : ?>
<?php echo “Guestbook is currently deactivated.”; ?>
<?php endif; ?>

Thanks,

Elliot
