I get a syntax err, line 60 near unexpected token ‘fi’. I attempt build a bike rental shop. Question, Below the if not available comment, add an if condition that checks if it’s empty. Put the send to main menu comment in it’s statements area. Seems simple but no coderoad progress. I moved the echo from the prev if statement. I add an else, and the prog runs but not for this qu. Dashboard, CodeRoad and gitpod not sync an issue?
Your code so far

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

Thank you for the advice. Also according to the code road prev question, when i select the Rent Menu I should see unavailable bikes too, but I only see the available ones.
