In your form, though Subform2 which is the parent Subform of the Table is flowed, still the Subform Stock is positioned. So the layout of the stock is fixed as Subform2 is a child elemet of Stock so it can flow unless the parent is flowed. So, if you make the parent Subform of Subform2 which is Stock in this, it will work. But be careful, doing show might change your layout. You need to re arrange.
