I'm got a label that includes a link to a PDF document. The location of the file is on a LAN drive.
However, the link will NOT function when viewing the form. You can click on it, but nothing happens. I know the URL is correct because I can right click, copy link location and then past it into a new window and the file opens.
I'm using IE11, (I know chrome and firefox do not allow file:// links)
If I put that same link into link list in SharePoint, it works fine, so I know its not a SharePoint issue.
