Error exporting from Ona

Welcome to the ODK forum, @Paul1! We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a picture as your avatar because it helps build community!

It sounds like @kailash is trying to upload completed submissions from a tablet to the server, but you are trying to download the compiled data of all submissions from the server to your desktop? Can you please confirm what you're trying to do, and let us know what type of server (Aggregate or Central) and version of server you are using? Also, if you can attach a screenshot, that could help.
