:point_right: Your buildList function is not returning a value.

Inside the function, you construct listHtml, but there's no return statement passing it back to the caller.

Also, when you create a list item in that function, the closing li tag is missing the slash.

 listHtml += "<li>" + arr[i] + "</li>" ;  // <-- note / added

Plus, you might want to add a "You got these questions wrong" header between the two calls to buildList.

That makes sense Steven. I bypassed the buildList function altogether cause it didn't seem to be doing anything. I didn't look to see WHY it wasn't doing anything.

html = "You got " + correctAnswers +  " "  + " question(s) right" ;
html += "<h2>You got these questions right </h2>"
html += right + " " + wrong; //here I added the arrays that you pushed the correct/incorrect answers to


print(html);

thanks it works now. thanks for pointing out the missing statements.
