Eq Null is not supported

Hi Guys - I wonder if anyone can help with the below error message? The app works fine when the error message is cleared. I know it has something to the code below that I have in the Area field... Both the area and store data are taken from a different source from the rest of the fields and the store field is dependent on the area field selected.

 

The code I have in the area field is                                                                 

SortByColumns(Distinct(Table2,Area),"Result")

 

Any help to resolve would be greatly appreciated.

    Ok, ChatGPT was helping 🙂

    If(IsBlank(Dropdown1_1.SelectedText.Value);Lagerbestand;Filter(Lagerbestand;Kunde=Dropdown1_1.SelectedText.Value))

    Re: Eq Null is not supported

    Hello,

     

    i have a similar problem with this string:

    Filter(Lagerbestand;Kunde=Dropdown1_1.SelectedText.Value)

    andthis:

    LookUp(Lagerbestand;Bezeichnung=Dropdown1_2.SelectedText.Value).Teilenummer

    but I am too stupid to adapt the If function to my code 😞

    In both cases, I am refering to an "earlier" dropdown. My table is in excel.

     

    I think the first solution is suitable for me, maybe someone could help me with the If funktion?

    Try this:

     

    If(IsBlank(DD_Area.Selected.Result),SortByColumns(Distinct(Table2,Site),"Result"),
    SortByColumns(Distinct(Filter(Table2,Area = DD_Area.Selected.Result),Site),"Result"))

     

    or this and let me know if you get your desired result:

     

    If(!IsBlank(DD_Area.Selected.Result),SortByColumns(Distinct(Filter(Table2,Area = DD_Area.Selected.Result),Site),"Result"))

    Yeah the error message disappears once an area is selected but when the app is live the error message shows up when users navigate onto the form.

    Does the error disappear when you select an area in DD_Area as it looks like the store error is saying it expects a value there based on the filter in order for it to work.
