I think I've tried something like that, although I'm not sure why it doesn't work
When the person click the arrow in gallery 1, this is the onselect code, where I try to store the name value
>Navigate('Manager System Landing Page', ScreenTransition.None, {selectedSection: ThisItem.Title})
Here is the code where I try to filter based on this, although it does not work
> Filter('Test Data',"System Manager"=selectedSection)
