I am thinking you have a dometic rollup awning for the popup. There is a screen room for it - look for it on the dometic website.
we did not get the screen room - it just looks like too much effort. and looking at other peoples set up when we walk around the campground - i rarely see the screen rooms. I do use a stand alone screen room to go over the picnic table.
