Why won't Horner[] work?


When I issue the command:

In:= Fit[ {{1,200},{200,0},{400,200}}, {1,x,x^2}, x]

Out:= 202.01 - 2.01508 x + 0.00502513 x^2

This seems good.  But when I do


In:= Horner[Fit[ {{1,200},{200,0},{400,200}}, {1,x,x^2}, x]]

Out:= Horner[202.01 - 2.01508 x + 0.00502513 x^2]


Why doesn't it evaluate the polynomial?  To I need to convert the
output of fit?

Thanks,
Paul
