News articles PHP part

• Bootstrap Grid system with "News-Updates"
   ○ The information comes from sql server
   ○ Contact Modal works as in the tutorial

I want to send the row id of the news article via $_GET
It works together with the Javascript identifier

I only get to see the Modal backdrop :(

    <div class = "container">
        <div class = "row">

            <?php
            $count = "3"; //Article count blox (example: 3  -->  3/12=4 means 4 news boxes will appear)


            $query = "SELECT * FROM news ORDER BY id DESC LIMIT 4";

            $result = mysql_query($query);
            if (!$result)
                {
                echo mysql_error() . $query;
