Any idea as to what I have done wrong because I am very confused right now. Thank you so much in advance for any help or advice

Answer 1

I am confused as well.
It would help if your data layer was separate from your display layer.
The error suggests that you are attempting to extract a result from a update. And that won't work with a standard update.
Where that is happening I have no idea.
