Hello! I’ve got a problem. The site doesn’t accept my code. I tried to change it, and followed the instructions, but couldn’t solve it. Here are the instructions

Thank you, I really appreciate your reply!

Hi there, what troubleshooting steps have you tried? (Eg have you tried to reset the ste? Any others?)

3

I reset few times, used different browsers (Google Chrome, Mozilla, Microsoft Edge).

4

I also cleaned the browser cash and tried a soft reset on the site.

5

I think you should move echo $AVAILABLE_BIKES from #get_available_bikes to #display_available bikes…The command should only be below #display_available_bikes…Have you tried that?

6

Here is something you have not tried yet:

Erase the line added.
Close the file.
Reset the step.
Open the file.
Add the line.

If the above doesn’t work, then try

Reset the step
Exit the whole project in the browser
Go to a different project in fCC and open it
Exit that one
Go to the bike project and open it
Retry the step

7

Yes, you are right. The solution is - remove the line from get_available_bikes to display_available_bikes. Many thanks!

8

just to clarify, the issue was that instead of moving the line, you had copied it only to the new location.
(once you deleted the old line, you were able to pass this?)

9

Yes, the problem is that I didn’t remove the line :grin:
