if you want help you need to share your updated code

Congrats on getting the sortBtn handled.
What’s the maximum number of times your outer loop should cycle? Look carefully at this code. Does this loop the number of times expected? Use console.log() to look at how your loop variable is incrementing.
How many pairs of numbers in the array should be checked in each cycle to see if they need to be swapped? Does this loop run the number of times expected? Again, use console.log() to look at your loop variable.
I’m ever so close I need to validate this div element to pass.
Please assist me on this last step
always post your updated code when asking for further help…we are not mind readers…well, i mean, maybe ILM is. 
Ok lol! I’ve only got steps 18 and 19 to complete as shown here,

You should be testing your code in the preview window and checking against how the example app behaves. Forget about what tests are not passing and focus on that!
Your sortBtn is borked again. I see the sort button before I interact with the page, then if I click it, I see this:
Please bear me the burden by providing the correct solutions otheriwse it might be a lengthy debugging process thanks.
No way. You are not putting out enough effort. A lengthy debugging process is exactly what you need to learn how to do. Your objective should be to learn how to code, not pass the tests.
Someone please end my misery for debugging this assignment.
if you are asking people to fix the code for you, that is not something that can happen
are you able to see what’s different between the two apps when testing your app and testing the example app?
Hmmm I dont know if. theres a bug from your side heres my code
