Why does Build & Run / Run is greyed out on Codeblocks for me.

Question

I just started this course, I wrote my first hello C++ program and was able to run and build. So now I wrote another program which I created new project for, but built & Run/ Run is greyed out. I have no idea why. I’m confused. Any help will be appreciated.
