Would you mind, breaking this one line into multiple while you edit it.

You then also see, that you didnt add the events as specified, because there are two divs in this row ;)

Should be:

    <td>
    	<div class="gensmall" style="float: {S_CONTENT_FLOW_BEGIN};">
    		<!-- IF postrow.U_POST_AUTHOR --><a href="{postrow.U_POST_AUTHOR}" class="imageset">{PROFILE_IMG}</a>&nbsp;<!-- ENDIF -->
    		<!-- IF postrow.U_PM --><a href="{postrow.U_PM}" class="imageset">{PM_IMG}</a>&nbsp;<!-- ENDIF -->
    		<!-- IF postrow.U_EMAIL --><a href="{postrow.U_EMAIL}" class="imageset">{EMAIL_IMG}</a>&nbsp;<!-- ENDIF -->
    	</div>
    	<div class="gensmall" style="float: {S_CONTENT_FLOW_END};">
    		<!-- EVENT viewtopic_body_post_buttons_before -->
    		<!-- IF not S_IS_BOT -->
    			<!-- IF postrow.U_EDIT --><a href="{postrow.U_EDIT}" class="imageset">{EDIT_IMG}</a> <!-- ENDIF -->
    			<!-- IF postrow.U_QUOTE --><a href="{postrow.U_QUOTE}" class="imageset">{QUOTE_IMG}</a> <!-- ENDIF -->
    		<!-- ENDIF -->
    		<!-- EVENT viewtopic_body_post_buttons_after -->
    	</div>
    </td>
