Triggers, Variables, States - activate button issue

I have created the slide below. the slide giving my problems is the first one (1.1).

I need the learners to review each of the layers before they move forward. They must click on transparent rectangle to open the layers. they then click on a marker to close the layer. once they have view all the layers the next marker should appear and allow them to click next.

I have done this 2 ways and it has not worked.

FIRST - states

Initial State of rectangles is DISABLED

When audio end change state of rectangle to NORMAL

When user clicks rectangle change state to VISITED

Show layer when user clicks rectangle

Change state of marker to normal when timeline ends IF rectangle... is equal to visited

SECOND - variables (variable is set to false)

Initial State of rectangles is DISABLED

When audio end change state of rectangle to NORMAL

               LAYER

               Set variable equal to true when the timeline starts

               Hide this layer when user clicks marker

Change state of marker to normal when timeline ends IF variable...is equal to true

Hope you can help
