How do you trigger the destructible mesh explosion in a blue print?

So I am fairly new to Unreal Engine and I’m trying to learn it little by little. Just this morning I finished a tutorial series from [Digital Tutors that walked me through making a really simple First Person Shooter.][1]

After I was done with the tutorial, I wanted to make the targets I placed around the level explode so I did some research and found how to generate a destructible mesh in UE. I created a new Blueprint Actor Class and set the destructible mesh as the display mesh in the components instead of a static mesh.

In the tutorial, it didn’t have me create an actual bullet and instead it just used a line trace to figure out where the “bullet” would hit and just spawned a particle effect at the point of collision instead. Each time there is a collision on the line trace, I have a variable keep track on each instance of the target blueprint. Once a target has been “hit” 3 times, it should explode into pieces, but I can’t seem to get it to actually explode.

I have tried looking to see if someone has the same issue, but I honestly don’t know what I’m doing wrong. I have attached a couple pictures of my event graph.

Any help would be appreciated!
