Fix this button

[Rob Zombie]

<span id="tyl_btn_{$post['pid']}"><a href="thankyoulike.php?action=add&amp;pid={$post['pid']}&amp;my_post_key={$mybb->post_code}" onclick="return thankyoulike.add({$post['pid']}, {$post['tid']});" title="{$lang->add_tyl}" id="tyl_a{$post['pid']}"><class="button postbit-button"><alt="{$lang->postbit_quote}" title={$lang->postbit_quote}/>Thanks</a></a></span>



What is wrong with that code? I need it to be a CSS button but it won't work...
