Triggers order

I agree with Judy and Phil. The trigger order is not the issue in your interaction. Both triggers at the top will fire as expected. The issue lies with where the variable 'DropCorrect' changes — it changes on the last correct layer. The 'Show layer - Summary' trigger will execute, but you won't see both the 'Summary' layer and the last correct layer at the same time unless the correct layers are set to show other layers. In that case, the correct layer and the Summary layer would overlap. I suggest moving the 'Show layer - Summary' trigger from the base layer to each correct layer, where the 'DropCorrect' variable actually changes to 1. 

Even if you managed to move this trigger all the way down on the base layer, it wouldn't make much difference — you'd likely run into another issue. I've attached a short video demonstrating how I think this interaction should end. Clicking the close button on the last correct layer should lead directly to the Summary layer.
