The reason it works on the instruction page is that you used a different variable other than "Click1" or "Click2." It also works on slide 2.5 because you used "Click1" and "Click2" variables for the first time. However, it won't work on slide 2.7 because you used the same variables ("Click1" and "Click2") that were already set to True on slide 2.5. The same issue occurs on slide 2.9 where "Click1" and "Click2" are already True. I suggest creating different variables for each interaction or resetting previously used variables to False when the timeline starts to ensure proper functionality from interaction to interaction.
