Curvefit issues [message #48198]

Hello,

I'm trying to fit a simple 1 parameter function to this data (see below
A,B); however, I am getting an error message " % GFUNCT: Incorrect
number of arguments." What's going on? It seems trivial, but I don' see
where it is faltering. Thanks for the help!

Jon

A=[0.910000, 0.460000, 0.870000,0.740000]
B=[4.46684,1.99526,28.1838, 11.2202]

weights = A
weights(*) = 1.0

;Provide an initial guess of the function's parameters.
G = 300.0

;Compute the parameters.
fit = CURVEFIT(A, B, weights, G, FUNCTION_NAME='gfunct')

PRINT, 'Function parameters: ', G
END

PRO gfunct, A, G, F
F = G * A^(2.0)
end
