Using repeating tables to display file links

I'm not sure if this is possible.
I've been tinkering around and have got very close.

I have a table which holds my file download information, such as file name, size and folder etc.

I've added a repeating table to my php download page and would like to display file download buttons in this table.

The page recordset exists so i'm able to populate the DFP wizard with folder and filename for the server behaviour.

Ok, so when all these are added to my page, i've got a working repeating table, where the file name is showing on the download button.

The recordset looks at a number of variables in the logged in users account. If the validation is good, then the recordset populates the repeating table with the appropriate files.

However, in my example, a user logs in but no matter which button is clicked, only the 1st file in the recordset is downloaded.

I'm not getting a unique file for each button.

Any guidance appreciated.
