在多个php脚本之间共享会话变量

我的问题是，当我使用会话变量在不同的PHP脚本之间复制数组元素时，什么都不会打印出来。以下是我的两个PHP文件。

file1.php

<?PHP
     session_start();
        $SQL = "SELECT * FROM tblquestions";
        if ($db_found) {
            $result = mysql_query($SQL);
            $numRows = mysql_num_rows($result); //return number of rows in the table
            echo '<FORM NAME ="form1" METHOD ="POST" ACTION ="file2.php">';
            for ($i = 1; $i <= 2; $i++)
            {
                $db_field = mysql_fetch_assoc($result);
                $qID[$i] = $db_field['QID'];
                $question[$i] = $db_field['Question'];
                $A[$i] = $db_field['qA'];
                $B[$i] = $db_field['qB'];
                $C[$i] = $db_field['qC'];
                echo '<P>';
                print $question[$i];
                echo '<P>';
                echo "<INPUT TYPE = 'Radio' Name = '".$qNum."'  value= 'A'>"; 
                print $A[$i];
                echo '<P>';
                echo  "<INPUT TYPE = 'Radio' Name = '".$qNum."'   value= 'B'>"; 
                print $B[$i];
                echo '<P>';
                echo  "<INPUT TYPE = 'Radio' Name = '".$qNum."'   value= 'C'>"; 
                print $C[$i];
                //if (isset($_POST[$name_Value]))
                $survey_Answers[$i-1] = $_POST[$qNum];
                print '</BR>'.$survey_Answers[$i-1]."</BR>";
                $question_Number = ltrim($qNum,'q');
                $question_Number++;
                $qNum ='q'.$question_Number;
            }
            echo '<p>';
            $_SESSION['answers'] = $survey_Answers;
            echo '<INPUT TYPE = "Submit" Name = "Submit1"  VALUE = "Click here to vote">';
            echo '</form>';
?>
On my Second file (file2.php), I have the following:

<?PHP
    session_start();
    if (isset($_POST['Submit1'])) {
            $results = $_SESSION['answers'];
            print $results[0];
}
?>

然而，在我的file2.php上，我得到了以下错误：未定义的偏移量：0，并且没有打印出任何内容。
