Hi Jason
I'm sure its me being dense, I've done as you suggested and I can now 'see' the form on the following page, I've set the upload to happen "before page load" as I've assumed that this will upload the selected file from the previous page however, the file isn't uploaded.
what I'm trying to do is to allow the uploading of a photo and then show a thumbnail of the image on the next page. the next step is to allow the user to either save the image (to a database) or abandon it (I'll be using the delete file option from webassist/file manipulation)
