I cannot access object value in a page from another page

Hi everyone, I have developed a form in LiveCycle 8.2. The form is used via web, HTML access, not a dynamic PDF. The form has 6 pages and I can not access the value of an element (anyone) who is on a page from another. I try to xfa.form.resolveNode ("Formulario.page1.element).rawValue (where "element" is the name of my form object), but it tells me that you can not access a null reference.

Thanks and regards
