Petroleum Table GUI ANN

Hi, I made two tables using the GUI. As shown in the figure, I need the user to fill in the columns of the first table (on the left), and the results to be shown in the other table(on the right). So what i need exactly is to enable the user to fill the whole table. Then, the simulate button will pass through neural network ,and the result will be displayed in the other table. What I have tried under the simulate push button

n=load('Rs\net.mat'); %to call the neural network

data = get(handles.table1, 'Data');

first_row = data(1,:); % trying to apply it first on the first row only

input=([first_row]'); % transposing the first row because the neural network takes columns not rows

ANN=sim(n.net,input); % simulate the network on the file input which is the first row

set(handles.table2,'data',ANN); % trying to make the asnwer appears in the second table cell (1,1)

This error appears when I press simulate "Inputs{1,1} is not numeric or logical."
