[Wordpress] conditional script

I got the if conditional script working but the problem is the <?php the_title(); ?> & <?php the_category(', ') ?> aren't displaying anyone know why?

<?php
$in_subcategory = false;
foreach( explode( "/", get_category_children( 8 ) ) as $child_category ) {
if(in_category($child_category))$in_subcategory = true;
}

if ( $in_subcategory || in_category( 8 ) ) {
echo '<p class="postmetadata alt">
						<?php the_title(); ?> is filed under <?php the_category(', ') ?> category. You can visit the <?php the_category(', ') ?> category to find all the episodes of this series.

				
';
} else {
echo '<span class="bad-cat">Not tasty! Not healthy!</span>';
}
?>

Code (markup):

 

didn't looked lot in code
but echo needs semicolan. and the_title() function itself in php script no need of php initiations

echo '<p class="postmetadata alt">
						<?php the_title(); ?> is filed under <?php the_category(', ') ?> category. You can visit the <?php the_category(', ') ?> category to find all the episodes of this series.

Your suggestion didn't work...

 

Are those codes within The Loop? From what I read in the WordPress Codex, i think the_category and the_title should be in The Loop.
