[Seven Skins]

I have tried following this: https://vborg.vbsupport.ru/showthread.php?t=228078 but no luck with what I am trying to do.
Most probably it will be simple solution but I can not get it to work. (I am new to writing plugins etc ...)

What I am trying to do is:

I have template name "TEST" with just simple HTML code <div>Some text</div>

And I just want this HTML to be inserted into e.g. footer template.

I have tried this in global_start plugin.

PHP Code:

$templater = vB_Template::create('TEST');
$test = $templater ->render();
vB_Template::preRegister('footer',array('test' => $test)); 


or

PHP Code:

$templater = vB_Template::create('TEST');
$templatevalues['test'] = $templater->render();
vB_Template::preRegister('footer', $test); 


And this in footer template.

PHP Code:

{vb:raw test} 


But that template does not show in footer template.


Thanks
