Dear James,
What attributes did you add to the survey?? If you create a Collect Earth survey without any further action this survey will be "empty" so nothing will be shown on the pop-up.
You can check how to generate a Collect Earth survey : [IN THIS VIDEO][1] , it is a bit long but I think you will understand the process better.
If there is already one survey that you like in the downloads (check [the list here][2] ) section of Collect Earth ( [IMPORTING AND EDITING A SURVEY][2] SURVEY][3] ) then you might want to use it, check this other video on how to import a survey :
If you still have problems send the CEP file so that we can check it ( you can reply to this post with a URL to the CEP file in Dropbox/Google Drive)
