I think the problem is that in your "prepare_output" function you can't just set "$this->block_data['mymodification']" to a template, it would have to be HTML at that point. So I think what you'd want to do is create a new template (in the Style Manager) and put your template code in there. Then make your prepare_output something like this:

	function prepare_output($id = '', $options = array())
	{
		eval('$this->block_data[mymodification] ="' . fetch_template('new_template_name') . '";');
	}

(but of course you want to replace new_template_name with whatever you actually name your template).
