Rotate Object using Mouse Input

I’m in the process of learning Blueprints, and I’m trying to create a quick test where I have a stationary camera that is looking at an object (see pink box in image below). I want the ability to use the mouse to click and drag on the object, which rotates the object I’m looking at. I have been looking at the following post:
[Rotate Object with MMB][1]

I have tried to implement the same graph in my blueprint, but I’m not getting any results. I’ve set up the level blueprint (Red) so that when I walk into the trigger box (Green), the new blueprint possesses my player and I’m looking through the new camera at the object. Here’s a schematic of what I have going on:

Here is what my level blueprint looks like:

Here is my object blueprint (patterned after the one in the post listed above). There is a camera and the stock chair in it.

If anyone has suggestions as to what I am doing wrong, I would love some input. Thanks for the help in advance!
