problem with reading forms

tempo33

I have two files.
In the first I have a form with 5 radio buttons only in html.
In the second I would like to read out this with php.
I use switch($old){ case 17: echo"under 17";break;
He cannot read the $old.
Please help me!
Thanks

not too sure what the problem is, the syntax looks ok to me, try echoing out $alter to see if it is holding anything or use the empty($alter) to see if it is empty however i find it easier to use if statement, a little easier to keep track of what you are doing

<?
if ($alter == "17")
{
echo "under 18";
}
else if ($alter == "20")
{
echo "under 21";
}
else
{
echo "whatever your conditions are, you can if statement them";
}
?>

I get the error undefined variable
Where should I define the variable in my script?
Thank you.
