Hello, I have a list in Sharepoint where multiple people are assigned to a sub-category which belongs to a category.
I'm trying to create an app in Power Apps which filters these people in a drop-down box based on what sub-category is selected in another drop-down box.
I've tried using standard formulas for filtering which worked in other situations, but it doesn't work for this one, it has an error under the equals sign saying "Invalid Argument Type"
Filter('Sub-Kategorijos', People.DisplayName = SubKategorijaDropDown.Selected.Title)
