Sorry to trouble the J-man with this. It is a bird’s nest.
There are some junk timelines in there from earlier stuff. The relevant timelines are:
Question Control – This works with the categories in the left panel, causing groups of questions in the right panel to appear.
Answer Category Control – This works with the right panel, causing controlling the visibility of the answers for each question to appear in the bottom panel.
Answers timeline – This controls the visibilit all answers for each category, grouped at different points in the timeline.
Example: Click on “Product” topic to move the Question Control timeline to 1 second, making the product questions visible. Click on the first question ("…product offerings") to move the Answers timeline to 1 second, making the first answer (the product offerings answer) visible.
The complexity is pretty intense (which is why a database solution would be preferable). Check out the screen shot. This time when I opened the file, two of the three hotspots (the text boxes) were knocked out of position in relation to the buttons.
