I am creating a visualizer that is going to display a meeting agenda on the left and a list of other documents on the right. This works if I put in the url of the agenda document, but I want to use the {{ agenda | documents_url }} for the source. How would I accomplish this?

Ex.1 object id="agendaPDF" data=" {{ agenda | documents_url }} " type="application/pdf" width="400px" height="600px"
