Hi @Dumitru
Could you please share more of your dropdown control's formula expression?
Do you want to patch the Dropdown selected value to your SQL table?
More information:
function-patch
For example I test as next:
Dropdown2.Items=["m","n","o","p"]
Button1.OnSelect=Patch('[dbo].[Tab_2019Test1]',Defaults('[dbo].[Tab_2019Test1]'),{ID:Value(TextInput1.Text),Nam:Dropdown2.Selected.Value})
(the green color ones are sql table name,control column name on my side, you can change to yours on your side,ID is the PK in my sql table)


Best Regards.
Yumia
