I am setting up a Parametric Study for different angles of attacks. I am in Results and creating a new expression for Lift. Once formed into an output parameter, will the following give me lift data?

Force_y(Normal Y)@aerofoil

Or do I use

forceNorm_y(Normal Y)@aerofoil

I do not know the difference between them, can someone help me please. Also how would I write down an expression for Drag and Moment then? When I make the expression for lift I get this error, what is this? I am new to parametric studies so I would appreciate some help.
