Internal 500 Error

Hi Guys,

When I try to add this code to my website, I get an internal server error. Not after I add it, BUT WHEN I CLICK SAVE CHANGES IN THE EDIT SNIPPET MENU. This is a common occurrence for me, and it happens to a wide range of code. What is happening? Here is one example.

add_shortcode( ‘shortcode_name’, function () {

$name_id = $_GET[‘name_id’];

if (isset($name_id)) {
$out = fish_loop_through_head_and_body_data ($name_id, “p”, “name_display”);
return $out;
}

return “”;

} );
