so this will be part of a multi page form? is that it?
if this is the case, the file upload should be on the last page. With a multi page form, if you have the file upload on the first page of the form, you may end up with abandoned files if the user doesn't continue through all pages of the form. The last page should contain the file filed and upload behavior and the insert behavior.
see this thread for details on how to create a multi page form:
