Simulating A Window Blind (Vertical movement )

I couldn’t get this to do anything even if i replace the special nodes that make it fire. I used a key press and still nothing. I’m not trying to create a Actor on the fly but trying to use a key press or the like to start an animation of the bottom blind rail, which would then move vertically catching each slat and adding to the bottom overall thickness, i guess. I would think this creates the stacking affect of pulling a string on a blind and the blind goes up. In any case, I will figure this out if I have to go to the rudamentry ways of programming, so be it. Sorry, I’m just way too ignorant of Unreal’s Nodes, but learning , none the less.
