he should be using the session when he is in the second part to store the variable since he is trying to create a 2 way submission.
Edited Code
you need to use POST or GET .
index.php
<form name="test" action="view.php" id="test" method="post">
<input type="radio" name="Whale" id="Whale" value="Whale"/>
<input type="radio" name="Shark" id="Shark" value="Shark"/>
<input type="submit" value="Order" />
</form>
view.php
<?php
$Whale=$_POST['Whale'];
$Shark=$_POST['Shark'];
$_SESSION['Whale']=$Whale;
$_SESSION['Shark']=$Shark;
echo 'You Select '.$Whale.'</br>';
echo 'You Select '.$Shark.'<br>';
?>
<form name="test" action="view2.php" id="test" method="post">
<input type="radio" name="Frozen" id="Frozen" value="Frozen"/>
<input type="radio" name="Iced" id="Iced" value="Iced"/>
<input type="submit" value="Order" />
</form>
view2.php
<?php
$Iced=$_POST['Iced'];
$Frozen=$_POST['Frozen'];
$Whale=$_SESSION['Whale'];
$Shark=$_SESSION['Shark'];
echo 'You Select '.$Whale.'</br> it has been'.$Iced;
echo 'You Select '.$Shark.'<br> it has been'.$Frozen;
?>
this is just a sample you will do the algorithm.. you may use POST or GET.
