can some one tell me why my ytrain and ytest is zero?

my labels are 100, 200 and 300

iam trying to find training error and test error but it gives me zeros

filename='FIFA2.xlsx';
A =xlsread(filename);
[m,n]=size(A);
T=A(:,1);
data=A(:,(2:end));
rows80=int32(floor(0.8 * m));
trainingset=A(1:rows80,2:n);
testset=A(rows80+1:end,2:n);
t=trainingset(1:rows80,1);
t_test=A(rows80+1:end,1);
net= newff(trainingset',t');
y=sim(net,trainingset');
%net.trainParam.epoch=20;
net= train(net,trainingset',t');
y=sim(net,trainingset')
y_test=sim(net,testset')
 p=0;
 y1=hardlim(y');
 %  hardlims(y_test);
 
 for(i=1:size(t,1))
     if(t(i,:)==y1(i,:))
    p=p+1;
    end
 end
ytrain =100*p/size(trainingset,1);
 q=0;
 y2=hardlim(y_test');
 for(j=1:size(t_test,1))
     if(t_test(j,:)==y2(j,:))
         q=q+1;
     end
 end
 ytest=100*q/size(t_test,1);
