call the_title inside a shortcode

Hello,

My php knowledge is very limited and I cannot make this work… So I have the following in my functions.php:

function preview( $atts, $content = null ) {
	return '<div><span></span>'.do_shortcode($content).'</div>';
}
add_shortcode("preview", "preview");

My question: how can I call the_title inside that span tag? Is it possible?

I thought it would be easy but my experiments return only several degrees of website destruction.

Thank you very much!
