Code:

<!-- BEGIN khungchuki -->
<div style="padding-top: 15px;"></div><div class="sig_02"><div class="sig_01"><div class="sig_03"></div></div></div><div class="sig"><div style="width: 100%;"><div class="signature_div">{postrow.displayed.SIGNATURE}</div></div></div><div class="sig_05"><div class="sig_04"><div class="sig_06"></div></div></div><!-- END khungchuki -->
