If you mix HTML with PHP, you always have to close your PHP statements before you continue with HTML:
<?php
if ( $p = page('community') ) :
$lblogs = $p
->children()
->listed()
->sortBy(‘date’, ‘asc’)
->filterBy(‘tags’, ‘podcast’, ‘,’)
->flip()
->offset(3)
->paginate(3);
foreach ( $lblogs as $article ) : ?>
<!-- html here -->
<?php endforeach; ?>
<?php endif; ?>
