SUM() function doesn't recognize a change in a Dropdown

(0) ShareShare
ReportReport
Posted on by Finnair 255

I have to consecutive dropdowns in a canvas app, Dropdown1 and Dropdown2.

Dropdown2 is a numeric value and it's changed according to Dropdown1 selected value.

 

Dropdown2 selected value is a part of a large SUM() function.

The problem is that the SUM() function is not updated when Dropdown1 is changed since the SUM() cannot "see" Dropdown2 changing.

 

How could I make Dropdown2 really "change" when changing Dropdown1? 

I don't want to add a hidden slider that corresponds the Dropdown2 value since I should change it to 90 places in the code.

    LookUp(Sort(Drop_Program,Time,SortOrder.Descending),BatchNr = Line_Drop3.SelectedText.Value,Program),
    LookUp(Sort(Drop_Program,Time,SortOrder.Descending),BatchNr = Line_Drop4.SelectedText.Value,Program),
    LookUp(Sort(Drop_Program,Time,SortOrder.Descending),BatchNr = Line_Drop5.SelectedText.Value,Program),
    LookUp(Sort(Drop_Program,Time,SortOrder.Descending),BatchNr = Line_Drop6.SelectedText.Value,Program)
    )
