Which project is this? I see another kind of error in the project that is currently active, which is because you have 1 Constant defined, but you didn't specify type for it. I can see that this type should be whole number, which means that the type is int. But I see another problem also - for the input field where you placed the Constant, you also checked that ckeckbox on the right side. Uncheck it, it's not needed when using a Constant.
