Yes, I knew that you can use the GUI, actually, that's how I found out that I had to add the 'instance' attribute to GetLocal: by creating the script using the GUI. However, I am trying to learn dx in script mode since for development of larger programs I belief that this a faster way to create them. Thanks for your reply.
