Finding and enabling the curve float for my blueprint(in the blueprint editor)

[TheRealPfloder]

So I’m currently implementing doors into my Game with watching this tutorial:
Unreal C++ Tutorial | How to make a Door - YouTube
But my Door wont animate and ive searched for solutions(im at 9:10 minutes), in the description he mentions something about enabling the curve float in the blueprint editor. Does somebody know where i can enable/find that curve float?

There isn’t a checkbox to “enable” the curve float. You have an actor blueprint that has your curve float type variable right? You will see that no curve is selected for it in the details window of your variable. You gotta click on there, and select the curve you wanna assign to it. Hope this helps!
