Would like to see an example of your data and also a manual mock up of the expected results you want to achieve.

To attach a file to your post,
click "Go advanced" (next to quick post),
scroll down until you see "manage Attachments",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.
