I have created a SP list and customized with Power Apps. I have look up fields, which I changed to Dropdowns.

When I am trying to Update datacards, I do not seem to get form to fill columns. Can anyone assist?

Datacard formula: 'Update'= Dropdown1.Selected.Result

see picture to see image with error.

  • Is the look-up column refer to the result column in that source list? Try with Dropdown1.selected.<columnName>

  • For some reason, it does not allow to select column name after selected. This is very strange :(

For lookup column, please try with the formula like below:

  Id: Value(Dropdown2.Selected.ID),
  Value: Value(Dropdown2.Selected.<ColumnName>)

I guess you remove the original data card and add a new dropdown for this whole data card. It works in my demo.
