ArcGIS Online

Hello!  Has anyone referenced a web map from ArcGIS Online and had success with the configurable pop up intergrating with Geocortex?  

My web map comes in perfectly, as well as the bookmarks.  But my pop ups do not.  The documentation states:

"Pop-ups: Pop-ups appear in the site as field settings for the layer. If the pop-up contains media links, the links are added to the layer as feature hyperlinks."

But when I go to my edit layer, fields tab, no items are configured.  

Thank you for any help or direction you can provide.
