ReQuering from Form

In form view, I am trying to list product components (from the "Drop Down Box") associated to a particular product. The problem I am having is when I go a new record and select a different product; I get the same components from the last product I had previously inputted. In other words, the components do not change with the product change. Does anyone have any idea what settings I need to change to that the components match that of the associated product in real time?

I have attached the file for your viewing. I also have the form open when file is opened.

Thanks in advance for your help.
