The codes not working =.=

I've followed all the instructor code. However in my browser showing error. How to solve the undefined $id? Where is the $id point to? Could you at least explain it?

Hi Samir!

On line fifteen of her code, $id is the parameter passed to the function (single_item_array) when it is used/called.

Does that make sense?

I hope that helps.

Stay safe and happy coding!
