HELP! This is to tricky to explain in a title, see detail in post!

Thanks for your time, see screenshot and project - how do I ensure the vertically tiled buttons along the right side (which are always visible) call a specific animation/event depending on which country button along the bottom is clicked? ie when UK is clicked the market share button will show market share info on the UK and so on?
