I don't understand what a conditional action with multiple decisions is. I tried to answer your question, but it seems that I didn't.
What I am doing is showing student progress. When a question is answered correctly, a variable for that question is assigned an new value. If it is answered incorrectly the variable gets assigned a different value.
I have a slide that shows what questions have been answered correctly, incorrectly, are not available, and are available to work on. These are the four variable values. Each question's progress state is displayed with an image. The variable value tells which image to show.
The advanced actions are the OnEnter for this slide. If I am starting with the first problem's variable, must I do separate "pages" of advanced actions. They probably aren't called "pages", but what I mean is, do I have to do a series of 4 if/then actions - all separate? If so, this seems like multiple conditional actions to me. When you say "a" conditional action and multiple decisions, I think of one action that is associated with more than one decision.
Can I do this in an easier way than doing doing 4 if/then pages for each variable?
I hope my question is clearer now.
