Since this question is about interactive PDFs, i've moved it to the PDF Generation section.
I will add the comment i've written in the french forum a few days ago:
"""
Sadly, the few people who are creating interactive pdfs with scribus, seem all to be beginners and do not stay around in the forums long enough to help each other...
"""
personally, for various reasons i hate interactive PDFs and you won't get much help from my side... sorry.
