Environment Variables

How do I get this correct its not showing me the final answer or giving me an error

Did you do the next steps yet? The “save the file” and “exit nano”, “clear the terminal” steps.

I am having exactly the same problem. My screen shows the same as ashnombre’s. I have saved the file, exited nano and cleared the screen. I cannot progress from here nor can I see the problem. I have recreated the bash_profile file in nano and reached the same point.
