This code looks like it came from a different challenge than the one linked by the button. The button challenge code works with a database of recipes and has methods associated with that, but this code seems to be working on a database of courses and has entirely different methods. The task objectives are obviously very different as well. This code clearly will not work for that challenge.

Starting the challenge over is probably the only way to deal with a snafu of this magnitude.

not really but i am stuck for days now failing to work it out, please help me out

please help me

As I was trying to explain, this code does not go with the challenge. It seems to be from a different challenge, or maybe from the video follow-along. It is not possible to pass this challenge using this code.

You will need to start the challenge over, and be sure you do not paste any code from your video follow-along project into the challenge. Start with the code the challenge gives you, and add only what the instructions ask for.

honestly i am stuck can you assist me

Yes, but only by pointing out that you need to start the challenge over, use the code the challenge gives you, and add only what the instructions ask for.

The code you have above does not go with the challenge and it's not possible to "fix" it to work.

i got right thanks
