Your code is not correct. Try:

<form action="#" method="post">
  Package: <select size="1" name="package">
<?php
$A = $B = null;
if(isset($_POST['submit']))
{
    switch ($_POST['package'])
    {
        case '50':
            $A = ' selected="selected"';
        break;
        case '75':
            $B = ' selected="selected"';
        break;
    }
}
?>
    <option value="50"<?php echo $A; ?>>Premium Package RM50 (with RMXX talktime)</option>
    <option value="75"<?php echo $B; ?>>Premium Package RM75 (with RMXX talktime)</option>
  </select><br />
  <input type="submit" name="submit" value="Submit" />
</form>
