    copied!<p>I'm currently working my way through a beginners php book and am trying to do an exercise that wants me to make a number guessing game. After failed attempts on my own I looked to the appendix for the answer. I've typed this code out multiple times and I believe is character for character what the answer key has and yet part of the script keeps appearing in the browser when I run the script. What am I missing? Thanks!</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"&gt; &lt;head&gt; &lt;title&gt;&lt;/title&gt; &lt;link rel="stylesheet" type="text/css" href="common.css" /&gt; &lt;/head&gt; &lt;body&gt; &lt;?php if ( isset($_POST["submitButton"] ) and isset( $_POST["guess"] ) ) { processForm(); } else { displayForm( rand( 1, 100 ) ); } function processForm() { $randNum = (int)$_POST["randNum"]; $guessLeft = (int)$_POST["guessLeft"]; $guess = (int)$_POST["guess"]; if ( $guess == $randNum ) { displaySuccess( $randNum ); } elseif ( $guess == 0 ) { displayFail( $randNum ); } elseif ( $guess &lt; $randNum ) { displayForm( $randNum, $guessLeft, "Too low, try again."); } else ( $guess &gt; $randNum ) { displayForm( $randNum, $guessLeft, "Too high, try again."); } } function displayForm( $randNum, $guessLeft=5, $message="") { ?&gt; &lt;form action="" method="post"&gt; &lt;div&gt; &lt;input type="hidden" name="randNum" value="&lt;?php echo $randNum?&gt;" /&gt; &lt;input type="hidden" name="guessLeft" value="&lt;?php echo $guessLeft?&gt;" /&gt; &lt;?php if ( $message ) echo "&lt;p&gt;$message&lt;/p&gt;" ?&gt; &lt;p&gt;Guess my number.
