PHP/MySQL Form Input - Quiz Game

I am creating a website which users can register for membership - once registered, the user can view the index.php page which contains a form:

Index.php

 <?php # index.php
 session_start();
 //check session first
 if (!isset($_SESSION['email'])){
 include ('../includes/header.php');
 }else
     {
 session_start();
 include ('../includes/header.php');
 require_once ('../../mysql_connect.php');
          $query = "SELECT * FROM answers ORDER BY RAND() LIMIT 1"; 
          $result = @mysql_query ($query);
          $num = mysql_num_rows($result);
          if ($num > 0) { // If it ran OK, display all the records.
              while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {      
 ?>

 <div class="newGame">
       <h2>Are you a Question Master?<hr /></h2>
       <h3 style="color:#000">Find Out Now!</h3>
 </div>
 <br />

 <div class="newGameContain">
       <form action="gameSubmit.php" method="post" autocomplete="off">
       <h2><? echo $row["Question"]."<hr />"; ?></h2>
       <h3>Enter Player Answers</h3>
              <p><input type="text" placeholder="Player 1" name="player1" value="<? echo $_POST['player1']; ?>" /> <input type="text" placeholder="Player 2" name="player2" value="<? echo $_POST['player2']; ?>" /></p>
              <p><input type="text" placeholder="Player 3" name="player3" value="<? echo $_POST['player3']; ?>" /> <input type="text" placeholder="Player 4" name="player4" value="<? echo $_POST['player4']; ?>" /></p>
              <p><input type="submit" class="submitButton" /> <input type="reset" class="resetButton" value="Reset" /> </p>
              <input type="hidden" name="questionId" value="<?php echo $row['ID']; ?>" />
              <input type="hidden" name"qAnswer" value="<?php echo $row["Answer"]; ?>" />
              <input type="hidden" name="submitted" value="TRUE" />
 </form>
 <p></p>
 </div>
 <br />


 <?php
                   } //end while statement
          } //end if statement
     mysql_close();
     //include the footer
     include ("../includes/footer.php");
 }
 ?>

Then on the form action page (gameSubmit.php) I have the following code:

gameSubmit.php

 <?php # index.php
 session_start();
 //check session first
 if (!isset($_SESSION['email'])){
 include ('../includes/header.php');
 }else
     {
 session_start();
 include ('../includes/header.php');
 require_once ('../../mysql_connect.php');
          $query = "SELECT * FROM answers ORDER BY RAND() LIMIT 1"; 
          $result = @mysql_query ($query);
          $num = mysql_num_rows($result);
               if ($num > 0) { // If it ran OK, display all the records.
                  while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {      
 ?>

 <? if (isset($_POST['submitted'])){
      $correct1Msg = "<div class='correct1Msg'><p style='color:#000;font-family:Arial, Helvetica, sans-serif;'>Player 1 entered the <span id='answerUnder'>correct answer</span>.</p></div><p></p>";
      $correct2Msg = "<div class='correct2Msg'><p style='color:#000;font-family:Arial, Helvetica, sans-serif;'>Player 2 entered the <span id='answerUnder'>correct answer</span>.</p></div><p></p>";
      $incorrect1Msg = "<div class='incorrect1Msg'><p style='color:#F00;font-family:Arial, Helvetica, sans-serif;'>Player 1 entered the <span id='answerUnder'>incorrect answer</span>.</p></div><p></p>";
      $incorrect2Msg = "<div class='incorrect2Msg'><p style='color:#F00;font-family:Arial, Helvetica, sans-serif;'>Player 2 entered the <span id='answerUnder'>incorrect answer</span>.</p></div><p></p>";

 $player1Answer = $_POST['player1'];
 $player2Answer = $_POST['player2'];
 $player3Answer = $_POST['player3'];
 $player4Answer = $_POST['player4'];

 $correctAnswer = $row['Answer'];
 $questionAnswer = $_POST['qAnswer'];
 $questionID = $row['ID'];
 $answeredID = $_POST['questionId'];
 $id1 = 1;
 $id2 = 2;
 $answer1 = "Red";
 $answer2 = "4";

         if ($player1Answer == $questionAnswer){
             echo $correct1Msg;
         }

         if ($player1Answer != $questionAnswer){
             echo $incorrect1Msg;
         }

         if ($questionID == "1" && $player2Answer == "Red"){
             echo $correct2Msg;
         }elseif ($questionID == "2" && $player2Answer == "4"){
             echo $correct2Msg;
         }else{
             echo $incorrect2Msg;
         }

         if ($questionID == "1" && $player3Answer == "Red"){
             echo $correct3Msg;
         }elseif ($questionID == "2" && $player3Answer == "4"){
             echo $correct3Msg;
         }else{
             echo $incorrect3Msg;
         }

         if ($questionID == "1" && $player4Answer == "Red"){
             echo $correct4Msg;
         }elseif ($questionID == "2" && $player4Answer == "4"){
             echo $correct4Msg;
         }else{
             echo $incorrect4Msg;
         }
 }
 ?>

 <?php
                   } //end while statement
          } //end if statement
     mysql_close();
     //include the footer
     include ("../includes/footer.php");
 }
 ?>

So as you can see, I'm attempting a few different methods of verifying the players answer with the last question. Basically, I am trying to make it so that when the user submits the initial form (located on index.php) - the form action (gameSubmit.php) will check each player answer with the correct answer from the question displayed on the last page (i.e. the question the players responded to) - I have tirelessly scoured the forums, websites, books and more for an answer to my problem; I just can't seem to find an explanation I understand or that works for me.
