The drop down: ddProduct.Selected.Title then changes. It has a Items:
SortByColumns(Filter(ProductList, CategoryName = ddCategory.Selected.Title And JobNumber = ddJob.Selected.Title), "Title")
I do not know why the drop down changes when I select the toggle. This changes to the first record each time, in the image below when the toggle "product materials pending" is toggled to true, the product drop down changes from "J02" to "J01".
