cascading dropdown choices are displayed in APP, but can not save to share point list

[Matthew_tu]

Hello! I have a problem to save choices of cascading dropdown to share point list.

1. I have created a "5s check" app by starting my data from share point list in phone layout (list name: 5S Check),like below pictures:

   

2. I create another share point list of "Department and line" which will be used as data source of drop down of "Dept." and "Machine"

3. And I change the formula in 2 drop downs in Items,

  Dept:  Distinct('Department and lines', 'Dept.')

 Machine:  Filter('Department and lines', 'Dept.' = DataCardValue8.Selected.Result)

 and change Data source of COMBO BOX of as below:

4. I have a test of app. It works. It can display the contents of 2 drop downs in app:

But, the contents of 2 drop downs can not be saved into share point list of "5S Check".

Pls help me to solve this problem. Thanks!

Hi @Matthew_tu ,

The detail you have not mentioned is the type of field you are writing back to. The Update of the relevant Data Card would depend on this - if a Text field (first)

DataCardValue8.Selected.Result

 or a Choice field

{Value:DataCardValue8.Selected.Result}

 second one (I am assuming the selected field is Machine) - Text

DataCardValue9.Selected.Machine

or Choice

{Value:DataCardValue9.Selected.Machine}

The type of field I am writing back to is listed below:

For the field of "Dept." : 

For the field of "Machine" :

@Matthew_tu ,

I need the type of field in your SharePoint data source - go to your Field Definition (although it looks like a Choice field) - did you try

{Value:DataCardValue8.Selected.Result}

and 

{Value:DataCardValue9.Selected.Machine}

Hi WarrenBelz,

The type of field "Dept."&"Machine" in my share point list of "5S Check" is "choice".

@Matthew_tu ,

Then the first code 

{Value:DataCardValue8.Selected.Result}

should certainly work on the card Update 

The second

{Value:DataCardValue9.Selected.Machine}

will work on the valid output of DataCardValue9.Selected.xxxx (I have assume Machine)
