Why is there a error message that says the numbers of input signals and networks inputs do not match?

Below is a copy of my code and I couldn't manage to get it to configure properly because of the error message. When I run the code it says the numbers of input signals and networks inputs do not match. Some help much appreciated.
x = linspace(0,10,100);
z1 = [0.001 1 1.5 2 2.335 2.5 3 4 5 6 7 8 10];
invx = 1./x;
invz = 1./z1;
z = [z1;invz];
t = Mg(z1,invz);
net = feedforwardnet;
net.numinputs = 2;
net.numLayers = 1;
net.inputConnect = [1 1];
net = configure(net,z,t);
NOTE: Mg is a separate file of some function of R and inverse R.
Thank you Greg for the comment, I apologise for the error, below is a copy of Mg.m file.
function value = Mg(r,inverseR)
B = 3.82045;
b = 1.31633;
beta = 2.17316;
C = -0.19641;
Rc = 2.30156;
c = 0.61347;
gamma = 1.79411;
D = 0.00082;
Rd = 1.83495;
d = 0.74887;
delta = 1.86846;
value = (-2.*inverseR).*(tanh(r)) + B.*(exp(-(r./b).^beta)) + C.*(exp(-(abs((r-Rc)./c).^gamma))) + D.*(exp(-(abs((r-Rd)./d).^delta)));
end

See my attachment
Note that typically, all you have to define is the input and target.
Use of CONFIGURE is UNNECESSARY
It can be as simple as this
See HELP FITNET
[ x, t ] = simplefit_dataset;
[ net tr y e ] = train( fitnet ,x, t );
MSE = mse(e)
