Having trouble with the state of items not working as intended with triggers.

The first problem is that the covers are between the icons and the text slider. (I wish you had named them Position 1, or Text1, rather than slider1. It made Julie [and me when I read your post] think you were moving from slide to slide.) That keeps the icons from interacting with the slider, so the triggers don't work. Change the triggers to reference the cover intersecting with the slider, and it works.

The other problem is that the white part of the icon is blank, so it doesn't catch the mouse click. That's unfortunate, because most people will click the white part. To fix it, I edited the state of the icons, and pasted a white triangle on them.

Check the attached sample.
