Cannot Assign GameplayEffect

[TweakySolution]

I’m trying to create a simple effect causing volume, similar to pain causing volume but it would fire a Gameplay Effect. However, I cannot assign any value to the variable I added. Nothing is appearing in the drop down even though I have multiple Gameplay Effects.

Any ideas as to the problem?

I’ll answer my own question: When selecting the variable type, it must be a class reference since no Gameplay Effect is instantiated .
