Container fields

[Mr H]

Hi everyone

I'm looking for a little assistance if possible. 
 
I have a container field which is displaying a pdf (store reference only) and a field which shows me the file path of that container field after I insert the file.
 

Is there a way of inserting the file path into the field and the container showing the pdf without me having to insert the file/reference?
