Only Getting a Null Value SharePoint List

[send2mark]

I have three lookup columns in a SharePoint list that reference one after another (Cascading dropdown). In the app it works perfectly, but when I submit it, the values are empty in the SharePoint list.

@send2mark ,
Can you show us the patch formula ? Or the update property if you use a form

It was created from a SharePoint list. So it is just SubmitForm(SharePointForm1) to save it. For the field, I do not have an option that is Update=. Sorry if that is not what you were looking for.

@send2mark 
select the data card to get the update property, not the combobox control.

Here you go.
