I don't know much about the Wii, but what video game are you trying to play? either the GameCube controller is not compatible with the game more than likely.
if you have an actual GameCube try plugging the controller into a GameCube and see if the controller works on an actual GameCube
Or
Try another try a GameCube game not a Wii game, I don't think the GameCube controller is compatible with Wii game playing on Wii.
I don't think you can play Wii games with an actual GameCube controller
here is a list o game compatible with classic controller but not sure if that includes an old GameCube controller.
