Tell us what’s happening:

Hello, my code is not passing test number 9. In my local run environment and in the preview on freeCodeCamp, both display ‘Status: INSUFFICIENT_FUNDS’.

Your code so far

The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

the tests will populate and change this, are you sure you are accounting for that?

3

If I declare
let cid
test 9 still fails.

4

can you provide your html? it is needed for debugging

5

Sure.

I found the code that was not passing.
changeDueEle.textContent += 'Status: INSUFFICIENT_FUNDS'
However the following code did pass.
changeDueEle.innerText = 'Status: INSUFFICIENT_FUNDS'

Thank you ilenia for taking time to look at my code.
