MATLAB: “Reference to non-existent field ‘Tabel1′”

Hi, im new in matlab, these are my codes,
%Kosongkan Tampilan
set(handles.InputA,'string','');
set(handles.InputB,'string','');
set(handles.InputC,'string','');
set(handles.InputD,'string','');
set(handles.InputE,'string','');
set(handles.InputF,'string','');
set(handles.Inputx1,'string','');
set(handles.Inputx2,'string','');
set(handles.x1final,'string','');
set(handles.x2final,'string','');
set(handles.InputTeliti,'string','');
%Ambil Data
A=str2double(get(handles.InputA,'string'));
B=str2double(get(handles.InputB,'string'));
C=str2double(get(handles.InputC,'string'));
D=str2double(get(handles.InputD,'string'));
E=str2double(get(handles.InputE,'string'));
F=str2double(get(handles.InputF,'string'));
x01=str2double(get(handles.Inputx1,'string'));
x02=str2double(get(handles.Inputx2,'string'));
T=str2num(get(handles.InputTeliti,'string'));
%Inisialisasi Variabel
syms  x x1 x2 L FL
%Program Utama
x=[x01 x02];
FX=A*x1^2+B*x2^2+C*x1*x2+D*x1+E*x2+F;
VF=[2*A*x(1)+C*x(2)+D;2*B*x(2)+C*x(1)+E];
norm=sqrt(VF(1)^2+VF(2)^2);
d=VF*-1;
xn=[x(1)+L*d(1);x(2)+L*d(2)];
FL=A*xn(1)^2+B*xn(2)^2+C*xn(1)*xn(2)+D*xn(1)+E*xn(2)+F;
Lamda=solve(diff(FL,L),0);
xn=[x(1)+Lamda*d(1);x(2)+Lamda*d(2)];
%Mengisi Tabel
set(handles.Tabel1,'data',num2cell(x(1)));
guidata(hObject, handles);
while double(norm) > double(T)
    x=xn
    VF=[2*A*x(1)+C*x(2)+D;2*B*x(2)+C*x(1)+E];
    norm=sqrt(VF(1)^2+VF(2)^2);
    d=VF*-1;
    xn=[x(1)+L*d(1);x(2)+L*d(2)];
    FL=A*xn(1)^2+B*xn(2)^2+C*xn(1)*xn(2)+D*xn(1)+E*xn(2)+F;
    Lamda=solve(diff(FL,L)==0,L);
    xn=[x(1)+Lamda*d(1);x(2)+Lamda*d(2)];
    Data=[norm xn(1) xn(2) Lamda];
    set(handles.Tabel,'string',Data);
    guidata(hObject, handles);
end
it's a steepest descent code, and when I pushed the push button, it said: Reference to non-existent field 'Tabel1'.
Error in SDNyoman>MULAI_Callback (line 144)
set(handles.Tabel1,'data',num2cell(x(1)));
Error in gui_mainfcn (line 96)
        feval(varargin{:});

Thank you.

Are you sure you didn't misspell it? Are you sure it's not Table1 instead of Tabel1?
