Not sure I am toggling category of income in the right manner.
For my part, in the Copy 2 computation worksheet, I have checked a different category (it was originally as General Income, so should be right, as Copy 1 was Passive Income), saved the return and did a Print/Print prview. This different times, checking different income categories.
Well everytime no success, that is only page 1 (Part I and II) is displayed.
