Action RPG Inventory System

I’ve been playing with the UI interface and have gotten some great results. What I’m trying to do now, unsuccessfully, is having the Interact Text (and eventually the Item Description Tooltip) spawn at the mouse location. I’m not having any luck.

I’m basically using the ‘Get Mouse Position Scaled by DPI’ Node with a ‘Get Player Controller’… to a ‘Make Vector 2D’… to a ‘Set Position in Viewport’. If I place a ‘Print’ node coming from the make vector, it shows the coordinates are updating in real time based on the cursor location, so the issue seems to be with the ‘Set Postion in Viewport’.

Any thoughts?
