### Your code so far

   arr.map(() => {

You are assigning a value to playerCards.innerHTML, the receiver of a value is on the left-hand side of the assignment +=.

receiver += "Some value"

element.property += someArray.map(() => {})

So yeah I did this myself, but it’s still failing, even though I think it should be correct.

playerCards.innerHTML += arr.map(() => {});

I’m trying to find out if anyone is having issues with saving the code for this step in the Building Football Team Cards project. I’m posting here because the step # is different. Here is my code in the screenshot. I’m not sure why it’s not saving and letting me move forward.
