Problem with hide/disable of subform field

Problem with hide/disable of subform field

I have the following statements in the on edit on load section of a form
   hide Order_Actions_subform.Courier_Count;
   hide Order_Actions_subform.Owner_Count;

They work as expected. However when I switch to scriptbuilder mode the statements are converted to
    hide Order_Actions_subform;
    hide Order_Actions_subform;

Which hides the entire subform!
