Making 'showdebug' variables public?

Ok so i think I have made some progress but i still cannot access the variable through blueprint,
I have changed WheeledVehicleMovementComponent script,
In the .h version i have added.


	/** Get The Long Slip */
	UFUNCTION(BlueprintCallable, Category = "Game|Components|WheeledVehicleMovement")
	float GetWheelLongSlip();


and i have also added the .cpp file to include


float UWheeledVehicleMovementComponent::GetWheelLongSlip() const
{
	return WheelsStates[w].longitudinalSlip;
}

But i simply cannot see the function/variable in blueprint.
If any1 has any suggestions that wouuld be great :stuck_out_tongue:
