Question: SphericalY

I have been unable to get any sensible output from the SphericalY function in MAPLE 12. With the command:  testp:=SphericalY(1,0,phi,theta), for example, the output line is just the command line. The only input parameter list that seems to give anything else is (0,0,0,0), which gives testp=0.
