anyone, any ideas how to solve? 
 
	i get following error on a website:
 
	Notice: Undefined variable: out in /var/sites/i/islandmemorials.co.uk/public_html/site/templates/includes/functions.php on line 43
 
	and this is a code in that very functions file:
 
<?php
  function numberOpen() {
    date_default_timezone_set("Europe/London");
    $currentHour = date('G');
    if($currentHour > 9 && $currentHour < 21) {
      $openFor = 21 - $currentHour;
      if($openFor > 1) {
        echo "We're currently open for another ".$openFor." hours, why not pop in?";
      } else {
        echo "Our lines are open for another hour - <a href=\"tel:+01983 857 600\">01983 857 600</a>";
      }
    } else {
      echo "Unfortunately, our lines are currently closed, but you can still send a message below";
    }
  }
	function getSubNav($pid) {
				$test =  wire('pages')->get("/services/");
				$parents =  wire('page')->parentID;
				$template = wire('page')->template;
				$out = '';
				//echo "pid".$pid."<BR>";
				//echo "parents".$parents."<BR>";
				//echo "template".$template."<BR>";
				$children = $test->children;
                
				foreach($children as $child) {
				     
				    $class = $child->id === $pid ? " active" : 'inactive';
                   
					if ($child->id === $pid ) {
						$class= 'active';
					}
					elseif ($template= "memorials"  &&  $child->id === $parents ) {
						$class= 'active';
					}
					$out .= "<li><a class='{$class}' href='{$child->url}'>{$child->title}</a></li>";
				}
				return $out;
	}
?>
	i suppose this has to do with a variable scope, but not sure
