Tick Box

Hi,

I have a screen in which I wish to record that a person has passed an exercise, to list unticked again which exercises remain to be taken.

I have created the triggers to display if the test has been successfully passed , these appear as ticks on my results screen. However the ticks are only appearing in one tick box ( a rectangle) whatever test has been taken,the trigger behind each rectangle refers to the state of the exercise when passed as true and the state to change to normal, ticked , when this state has been achieved. Why do the other triggers not work ?
