Can't get a scroll interaction (on a section) to show/hide a fixed element?

Hi,

So, I need two buttons to show when I reach a particular section (classname: “2ndvideoonwards”
)
These two buttons are inside a div (classname: “topcontrols Copy”) plus it has an (initial appearance) hidden interaction applied to it.

Also, when I move back up (or scroll out of view of “2ndvideoonwards”, I need “topcontrols Copy” to disappear.

I can’t seem to make this work.

Can someone please help and at least point me in the right direction.

Also below you can find snapshots of interactions on both the elements:

Hi @Waldo - can you please take a look?
