Subject:   Display selected value in radio buttons when previous button is clicked

Hello


I have created some evaluation pages. It is one page when i am keeping track of question and displaying the question when next and previous is clicked. I have a problem of displaying the previously selected values in the radio buttons when going back and forward. Here is the code i used.


function displayQuestionOne() {
$answer = $_SESSION['answerArray'][0];
echo "Answer".$answer;
$choice1 = $choice2 = $choice3 = $choice4 = '';
if ($answer == "Opens") $choice1='checked';
if ($answer == "Opened") $choice2='checked';
if ($answer == "Open") $choice3='checked';
if ($answer == "will opened") $choice4='checked';


?>
<tr>
<td colspan="3">

Select the correct answer

</td>
<td width="13%"> </td>
</tr>
<tr>
<td width="7%">1.</td>
<td colspan="2">Sample Question 1</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td colspan="2">


<input type="radio" name="Question" value="Opens" <? $choice1 ?> /> Opens

<input type="radio" name="Question" value="Opened" /> Opened

<input type="radio" name="Question" value="Open" /> Open

<input type="radio" name="Question" value="will opened" /> will opened

</td>
<td> </td>
</tr>
<?


}


?>



Any help is appreciated.


Thanks

    Sorry. Here is the correct code.
    // This displays Question 0
    function displayQuestionOne() {
    $answer = $_SESSION['answerArray'][0];
    echo "Answer".$answer;
    $choice1 = $choice2 = $choice3 = $choice4 = '';
    if ($answer == "Opens") $choice1='checked';
    if ($answer == "Opened") $choice2='checked';
    if ($answer == "Open") $choice3='checked';
    if ($answer == "will opened") $choice4='checked';
    echo "Choice 1".$choice1."
    ";
    echo "Choice 2".$choice2."
    ";
    echo "Choice 3".$choice3."
    ";
    echo "Choice 4".$choice4."
    ";
