All of the checkboxes and radio buttons seem to show for me. I tried on my iphone and on my desktop. What browser are you using when they don't show? How can I reproduce the problem?
The header error I can see...
You have this on lines 7-13 of your confirm.php page:
<style type="text/css" media="all">
You can't have html code above the <html> tag. That code should probably be down close to line 555.
