New problem Cascading dropdown with choice type columns

[s44]

Hello, I have 2 SharePoint lists with "Choice" type columns that look like this : 

I would like to create "Cascading Dropdown" on a form with Power Apps, by connecting to my SharePoint lists. But I don't understand at all how to do this with choice type columns. Everything I try fails. 😞

For example, I tried to write this:

But when I launch my Power Apps form, it doesn't work, the items of "Filiere" are empty :

Can you help me please ? Thanks in advance ><

Hi @s44 ,

Try this

Distinct(
   AddColumns(
      Filter(
         'Categorie et Filiere'; 
         Categorie.Value = DataCardValue2.Selected.Value
      ),
      "FiliereValue",
      Filiere.Value
   ),
   FiliereValue
).Result

I just tried your solution, but I still have the same problem. The items of "Filiere" are empty on the Power Apps form 😞 @WarrenBelz

What Shane Young does in his video doesn't work. Because I have ComboBoxes and not DropDowns @Pavan_Mani_Deep

Indeed the video does not offer any solution to solve your problem. But I'm just as stuck as you. It's a very strange problem.

I've been stuck for 2 days 😞

@s44 ,

How many items are in the list 'Categorie et Filiere' ? The Distinct filter is not Delegable

[s44]

I have 7 lines ^^ @WarrenBelz

@s44 ,

The syntax is valid - I just did a test here to confirm this as below - Items of the second combo box

and the output

Are you sure this is not a data issue?
