Subforms not appearing after form is saved and reopened with corresponding selected checkboxes, which have been scripted to make

I have created a form in Designer 7 and it is interactive when viewed as a PDF. Some subforms are hidden, unless triggered (via check box)to become visible. Once the form is saved, closed, and then reopened, the checked box does remain checked but the correspinding subform that the clicked check box is supposed to make visible is hidden again (this is the problem). I want the user to be able to check their boxes, have those boxes' appropriate subforms appear, save that form, and then reopen it so that they can see the subforms that had appeared originally for them when the boxes were first checked. In other words, how do I make the subforms that are scripted to be hidden unnless a corresponding clicked checkbox makes it visible REMAIN VISIBLE after the check box is selected, the form is saved and closed, and then reopened?
