Problem view with echo elgg_view_module()

Hello guys, I have a problem.
I have a view (results.php) where there's a function and then its execution:

//execution
echo elgg_view_module('aside', $title_f);
function($entita_f, $tags_principale1, $url1);

I would like to put the function's results in a page and I have:

$title = "Oggetti correlati";
$content .= elgg_view_title($title);
$content .= elgg_view_form("gesp/results");

but I cant see anything. Is there a problem about echo elgg_view_module('aside', $title_f); ??
Because I tried to put results on the sidebar and I can see them.

Thank you for your help.
