How can i play a random animation of my choosing on a skeletal mesh inside a blueprint?

Hi,

Ive been trying to figure this out for some time now with no success. I dont come from a programming background but i have fair competence in UE4.

Im trying to place skeletal meshes, playing random animations from an array, along a spline.

I got halfway there following this tutorial - Studying Spline Components In Unreal Engine 4

No matter what i do, none of the nodes within the BP will allow me to attach a “play animation sequence” onto a skeletal mesh.

Any ideas here?

im not sure how animation blueprints would work for me here? I dont need all of the control involved.

Ill post my BP below.
Thanks in advance.
