Variable does not display

Hi,
I took advantage of the guide: https://net.tutsplus.com/tutorials/wordpress/how-to-create-a-better-wordpress-options-panel/

Everything works, but these settings appear on the blog.

In my functions.php file:

array( "name" => "Footer admin mail",
	"desc" => "E-mail admina.",
	"id" => $shortname."_footer_mail",
	"type" => "text",
	"std" => ""),

and in the footer.php file:

<form action="<?php echo stripslashes(get_option('bl_footer_mail')); ?>" id="contactForm" method="post">

Why bl_footer_mail is not displayed?
Even in the loop, anywhere.

Please help.
