Setting Collision from Trigger?

How do i set the collision of one trigger from another?

I’ve got 2 triggers in my map but I want the second trigger to function only after the player has triggered the first one.

What am I doing wrong?

Here’s my Level BP setup:

Here’s the collision settings for both triggers:

TriggerBox >> Collision >> Collision presets >> “Trigger”

TriggerBox2 >> Collision >> Collision presets >> “Custom”

The first trigger works but the second doesnt, I’d appreciate some help!
