Hi Daniel and Dieu,

Finally after much trial and error I finally got it working. I created a user-provided service and then called on it from my application. I've documented the steps for anyone else wanting to know how to work with these variables (clearer documentation with examples maybe?).

Here's the documentation and example application: https://gist.github.com/jonasrosland/08b5758eaa9098a81cf8

Thanks for all your help!

Best regards,
Jonas Rosland
