Assistance needing Vive Controller to work with UMG without point and click

Ok just updating what I have been trying, or more to the point, testing. I am still unable to have the buttons swap between A, B, C etc. I ran a test and had the UMG simply print a string if one of the options from the controller was pressed once the menu was opened. Now the option once you pressed an button worked (which at this stage is the button it is focused on when it’s opened), which is set to the Trigger on the Vive Controller. So it’s through a branch which is simply getting the player controller and checking “Is Input Key Down” and that input key is Vive (R) Trigger. However if I set up a test if I test for input key of “Vive (R) Trackpad Right” or “Vive (R) Trackpad Left” it doesn’t fire. It’s as though the buttons don’t exist on the trackpad. I have checked the options do work by setting an Action Input and from the controller pawn simply call the action and print a string to the screen, this works. I haven’t yet tested other options on the Vive Controller as they are set to do certain functions so I will disable and try but any ideas would be appreciated.

Thanks
