Hello and welcome! Sorry for the late reply due to summer vacation.
I just created a similar setup and everything works correctly here, but it really depends on what is that is not working in your case.
Please note that the Mouse (Self) Event, expects a Mouse Click ON the assigned object (in this case “Self”) which has to of course have a collider attached. If you instead only meant Mouse Click “anywhere in the screen”, you will need to use the “Mouse Button Event”.
Is this indeed the case, or something entirely different?
