spfa on "[Theme: Customizr] Change footer Credit"

In my child theme I have the following files:

functions.pho
style.css
screenshot.png

the info inside my function php is as follows:

<?php
/**
add_filter('tc_credits_display', 'my_custom_credits');
function my_custom_credits(){
$credits = '';
$newline_credits = '';
return '
<div class="span4 credits">
<p> · © '.esc_attr( date( 'Y' ) ).' '.esc_attr(get_bloginfo()).' · '.($credits ? $credits : 'Developed by SPFA Design').' ·'.($newline_credits ? '
· '.$newline_credits.' ·' : '').'</p> </div>';
}
*/

`

Does this help? What else needs to be here, added, deleted?
