I'm Map the Movement
I'm having trouble making an app to show you what's going on on Twitter in certain locations on the map. I'm learning the student-led behavior tracker for YR Media and I'm stuck with this code and don't know what to do. I don't know even if I look at the reference book, please let me know

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .

Please let me know whether these Blocks are correct. 
It works until it makes you sign into X (Twitter?) so you have to have an account to see the results.
