why do i get this error? iam trying to train a neural network.80%of my data is training data and the rest is test.

Error using network/train (line 340)

Inputs and targets have different numbers of samples.

Error in Untitled3 (line 20)

net= train(net,set',t');

this is my code.

clc
clear all
close all
filename='FIFA2.xlsx';
A =xlsread(filename);
[m,n]=size(A);
T=A(:,1);
data=A(:,(2:end));
[m,n]=size(A);
rows=int32(floor(0.8 * m));
set=A(1:rows,:);
testset=A(rows+1:end,2:n);
t=set(1:rows);
t_test=testset(rows:end);
net= newff(set',t');
y=sim(net,set');
% net.trainParam.epoch=20;
net= train(net,set',t');
y=sim(net,set');
hardlims(y);
