Upload image file not working

I am having a problem getting images to upload.

I am trying to change my "edit profile" page to allow users to upload a new image. I have followed the tutorial, but it says in the last step to open up the "WA Update Record" server behaviour. I do not have that server behaviour, the only thing I have that comes close is "Update Record (WAATKUpdateForm, members, members). I created the form with Data Assist so I'm not sure why I don't have the right server behaviour.

So, my questions are:

1) does DFP only work with Data Assist? or is it supposed to work with any update form?

2) is there something I'm missing that allows a new file to be uploaded?

My update page works great, for every element except the image. Without adding the DFP functionality, I can change the name of the image file, and it updates in the database, but I cannot of course, upload a new image.

When I try to add the DFP functionality to upload an image, it deleted the information currently in the database and doesn't upload the picture.

Any help would be appreciated, I'm tearing my hair out.

p.s. I did add the debug info to the page, but since I'm new to this, it doesn't really help me.
