Using template hooks vs. manual insertion into template

[Cloud-Warrior]

Thanks Opstery, good hint, but still I couldn't get it to work.

Now I have it like this:

$template_hook['usercp_options_privacy'] .='<fieldset class="fieldset">
	<legend><label for="cb_allowsioc">Export SHA1</label></legend>
	<table cellpadding="0" cellspacing="'.$stylevar[formspacer].'" border="0" width="100%">
	<tr>
		<td>
			Export encrypted version of my e-mail address
		</td>
	</tr>
	<tr>
		<td><label for="cb_allowsioc"><input type="checkbox" name="siocbitoptions[allowsioc]" value="1" id="cb_allowsioc" '.$checked[allowsioc].' />Export SHA1</label><input type="hidden" name="set_options[allowsioc]" value="1" /></td>
	</tr>
	</table>
</fieldset> ';

This should be right and $stylevar[formspacer] does get expanded. But still no checked checkbox - everything gets saved correctly though when I check the box (it also did that before).

Somehow I suspect there is another obvious thing I am missing - any other suggestions what might be wrong? Maybe another hook location instead of global_start?
