Hi all. We created a project in AE 2020, but need to open it on another machine in AE 2018 (15.x). When we opened the file in 2018, the simple expression in our comp for a slider control returned an error. See the attached images for more info.
Odd thing is, when we opened the same "back-saved" file in AE 2019, it opened fine and worked as expected. We even tried (in the 2015 AE project file) deleting and recreating the slider effect, re-writing the expression from scratch, and even deleting and re-adding the position keyframes to which the expression is referencing. Nothing seemed to fix the error. So all we can figure is that something in the file itself isn't being translated right from 2020 to 2018.
I posted the two AE files in a Zip folder to Google drive. Here's a direct link:

Any help is appreciated!
