Player character cast - 3D widget rotation no working

I’m new to blueprints and please excuse me if I’m making a right mess of this. Basicly I’m trying to get a 3D widget menu system working for the Vive as it doesn’t support viewport menus. I’ve attached the 3d widget as a player character component. Originally I wanted the menu to appear and disappear from you click the pause key and resume button but having problems with that I decided to hide the menu behind/under the character and rotate it into view when needed. I seem to work in terms of appearing when i press the pause key but I can’t get it to rotate away again when clicking resume.

Can someone please point out where I’m going wrong.

Alternatively, if anyone knows how to make a 3D widget attached to a character appear and disappear that would be equally useful.
