Error: FCN does not return an info object.

I have this code:

    rng('default')
    x = input;
    t = output;
    trainFcn = 'traingdm';  % Gradient descent with momentum backpropagation.

    % Create a Fitting Network
      hiddenLayerSize = 50;
      net = fitnet(hiddenLayerSize,trainFcn);

    % Setup Division of Data for Training, Validation, Testing
      net.divideFcn = 'dividerand';
      net.divideParam.trainRatio = 70/100;
      net.divideParam.valRatio = 15/100;
      net.divideParam.testRatio = 15/100;
      net.trainParam.epochs = 10000;
      net.trainParam.lr = 0.01;
      net.trainParam.mc = 0.9;

    % Train the Network
      [net,tr] = train(net,x,t);
    % Test the Network
      y = net(x);
      e = gsubtract(t,y);
      performance = perform(net,t,y)
    % View the Network
      view(net)

But when I run it I get this error:

Error using fitnet (line 69)
FCN does not return an info object.

Error in traingdm (line 20)
net = fitnet(hiddenLayerSize,trainFcn);

What part am I doing wrong?

[CLHE]

try to use only net=fitnet, delete the bracket. it should run fine.
