I cannot make this work at all. I have set up my TOC the way I want it, which is as a "Seperate" style (not overlay). But in the Project menu Skin Editor I have unchecked the "Show TOC" checkbox because I do not want the TOC to display at the start. At the end of my e-learning and the user has reached a summary page, I now want to give the user access to the TOC. So my On Enter action for that slide is to assign the variable cpCmndTOCVisisble to 1, just as you explain. But this seems to do nothing; no TOC appears. I don't have a TOC button in my bottom toolbar and I don't have a chevron in the top-right as I would if I ahd selected to show a TOC from the project with a style of Overlay.
What am I not understanding?
