I think you need to check the structure of what you are doing.
I can see a problem with how you are doing it.
This isn't to say it won't work.
Just how I think, there is a different way to do it and it is a lot easier.
And I don't mean that with the code. I mean with how you are doing it with the code you posted - well.... reading around it and what I finally got it to do.
It introduced _feedback_ where things were done multiple times over for no benefit to the need - as I see it.

Yeah, but I shall go back to what I said: there is an easier way to do it.
Alas I can't add a lot of blank lines. This site forces only single lines, so I can't put a big _SPOILER_ gap and a few thoughts on some things I can see as problematic.
But I don't want to show you this as it won't make you learn.
Being _spoon fed_ the answer (or **an** answer) isn't the best way to learn.
Alas you need to go through the hard times to learn.
I am still learning after ..... 2 years.
I think I am only just off my _learner plates_.

The reason for this is that the slider doesn't work if the data doesn't change.
without explaining it... I'm sorry to confused by thoughtless selection.
I think the way you guys told me is good.
I felt a lack of basic and node usage.
I'll study the basics again.
start on my own without lean on other people 🧐.
After that, I will identify unnecessary parts and exclude them step by step. THX
