TF Course - IDE / referencing Issues

Hello all,

I just opened the TF ROS 101 course and it has loaded a past IDE session from another course I have taken on the Construct and the input code given within Unit 2 - TF Basics fails to run (image attached).
How do I get the TF module to work properly / make a fresh (correctly referenced) IDE environment/workspace?



Could you check now? We have a new version and this should be solved
