Hi @LKAY900 :

The point is that the combo box's DefaultSelecteditems property hasn't been set.Every time the form is submitted, all the controls in the form will be reset, because the DefaultSelecteditems property of this combo box is empty, so it will be reset to empty.

Could you tell me:

What is the data type of the "使用辅具" field in the target data source of your Form?

What is the "卡片：使用辅具"‘s update property?

What is the "资料库"’s data structure?

Best Regard,

Hi @v-bofeng-msft
Sorry, I don’t know if your question is correct.
1. What is the data type of the "use aids" field in the target data source of your Form?
ans: string
2. What is the "Card: Use aids"’s update property?
ans: record the content used by the individual, there will be different project requirements with the change of the individual's body, confirm whether the content needs to be updated after each visit
