Hi, the button action is to reset the form (but not the whole form).
You can't press the button but you can imitate that action using this code:
this.resetForm(["Field1", "Field2", "Field3"]);
This will reset those three fields, for example.
I would look at writing a document level function to perform that task and then call that function for the button action or any place I need to perform that specific action.
