In my php code you can see that the function of isset() that set that when your PHP code run. In your code you mention $radioVal = $_POST["MyRadio"]; where MyRadio is undefined index for PHP. Here when we submit the form then submit call the PHP code without any lag and you also use the double form. This is wrong for this code.
