Input error

Hi! I use standard 3rd person controller and I want to add crouch, but I have a bug in input code. I have no idea what is wrong.

InputComponent->BindAction(“Crouch”,
IE_Pressed, this,
&ACharacter::Crouch);
InputComponent->BindAction(“UnCrouch”,
IE_Released, this,
&ACharacter::UnCrouch);

Did you set the inputs in the projects settings, for both pressed and released, and set Can Crouch to true?
