Hi @Anonymous,
Have you solved your problem?
Do you want to click the Operation button to navigate to the Operation related page and populate the selected date into a Label or some other control?
Could you please share a bit more about your scenario?
I think you should set the Operation Button OnSelect property as below:
Set(ReportDate,DatePicker1.SelectedDate);Navigate(OperationPageScreen)
set the Transportation Button OnSelect property as below:
Set(Transportation,Dropdown.Selected.Value);//Here depends on how you set the Items of the Dropdown
Navigate(TransportationPageScreen)
Then on the Operation screen and Transportation screen, populate a Label or a TextInput Default property with the two variables represently.
