Try the following:
<html>
<head>
<title>corners in running</title>
</head>
<body>
<form method="post" action="<?php echo $PHP_SELF."?post";?>">
Corners:<br />
10:<input type="radio" value="10" name="wholecorners">
11:<input type="radio" value="11" name="wholecorners"><br />
<input type="submit" value="submit" name="submit">
</form>
<?php
if($_POST['submit'] && isset($_GET['post'])) {
$corners = $_POST["wholecorners"];
if($corners>=10 && $corners<=10.99) {header('Location: http://maidenerleghweather.com/corners1.php?var1=' . $corners. '&var2='.$time ); }
if($corners>=11 && $corners<=11.99) {header('Location: http://maidenerleghweather.com/corners2.php?var1=' . $corners. '&var2='.$time ); }
}
?>
Code is not tested!
It should, if i remember right, only redirect you if the submit button has been activated, and extra secure by setting a ?post in the URL.
