Hidden Drop Down List and Text Field Won't Allow User Selection/Entry. What to do?

I have a form with four radio buttons, E,F,G, and H. Using subforms and javasript on Calculate, I can get all buttons to reveal the correct hidden subform fields. But, the drop menu and user entry text fields will not allow user interaction/entry. Is there a simple way to make those fields active for user entry? The forms were originally created in LiveCycle Designer 8.2.1
