retrieve upload in details page?

Hi,
I have successfully created a file upload option on an insert page that uploads to a folder and inserts filename into a table.

On the details page I added a field and dragged the filename field from the recordset onto the form, this shows the filename but doesn't allow the user to view the file. I can view images if required by inserting image then choosing dynamic field, but all my uploads are documents, pdfs, docs etc,

Where possible I need to allow users to view all documents they have uploaded and add more via the update page.

If user has uploaded 3 pdfs these would need to be linked on the details page, clicking would open:

CaseDocuments/upload1.pdf
CaseDocuments/upload2.pdf
CaseDocuments/upload3.pdf

Any help appreciated really cannot find any documentation on DFP whatsoever.

Regards
