Hi @Todd_Meng! As you are new to the community, when you get a chance, please introduce yourself here.
I’d also encourage you to add a real picture as your avatar because it helps build community!
In terms of your question, if you can share your form, that would be very helpful. Does the error message refer to a particular row or are there other things you changed that might be causing the problem? As well as the data_value and display.title.text you do need a choice_list_name as well.
