			echo "</div>"; 
		}  
	}  

include("footer.php");
?>

$sql = "SELECT * from updates ORDER BY id DESC LIMIT 3";
$stmt = $link->prepare($sql);
$stmt->execute();
$result = $stmt->get_result(); 

if ($result->num_rows = '0') {

	echo "There haven't been any updates yet.";
  
} else {

	echo "There are news posts";
}

Gives me the error "Cannot write property in /home/evoarena/public_html/Dev/news.php:14 ", line 14 is the if statement. How can I fix it?
