Submission form - attachment

Hi,

I have created a submission form (http://illumemagazine.com/zine/submit.php) where user can submit a general inquiry with standard text boxes (name, email, comment). I have included an upload field, but I am getting errors when users try to send an attachment through.

Error: MySQL Error Creating Record:
Unknown column 'uploaded_file' in 'field list'

I have attached the form to this thread.

On a similar note, is it possible to create a separate submission form so users can submit an article directly from the site, and when they attach an image, instead of coming through as an attachment, it shows up more like an upload (like a standard article). So all the admin has to do is to approve the content and it shows up on the homepage...

I also have apps due to release on ipad, iphone & android platforms... Part of the apps encourage user submission of photo/video...with written captions. This feature will directly tie in to the submission form. So any help with be appreciated!
