Split screen website scroll to top button not working

[pagagne]

Hi! Thanks for all the work you guys do!

I'm just having a little issue on a split screen website. When making a scroll to top button, the button does not work..

I tried a few different ways using Java Script but still can't figure it out.. Wondering if you'd have any insights..

Thanks so much for your help!
