What is the meaning of "There is no property on the UIControl class."?

Dear All, I have sets of data and I need to import them to the function based on the month variable, I wrote this code on the gui to code the popupmenu1 I have, but still doesnt work and gives errors, any ideas please ? I have two cases, one is January and the 2nd is July.

% --- Executes on selection change in popupmenu1.
function popupmenu1_Callback(hObject, eventdata, handles)
% hObject    handle to popupmenu1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns popupmenu1 contents as cell array
%        contents{get(hObject,'Value')} returns selected item from popupmenu1
directory=dir('*.Y07');
count=0;

for K = 1 : length(directory)
    filename = directory(K).name;
    fileID = fopen(filename,'r');
    formatSpec = '%s';
    A_cell = textscan(fileID,formatSpec);
    A=char(A_cell{1,1}{:,:});
    A(find(isnan(A)))=0;

      [rows,columns]=size(A);
      if columns~=105
          ArrayTemp=zeros(rows,105);
          ArrayTemp(1:rows,1:columns)=A;
          A=ArrayTemp;
          A=char(A);
          A(isspace(A)) = '0';
      end

      x1=filename;
      xtr=strcat('C:\Users\maa285\Desktop\New folder (2)\',x1);
      fid = fopen( xtr, 'wt' );

      Month_of_Data = A(:,14:15);
      Vehicle_Class = A(:,20:21);

      Ans_7=str2num(Month_of_Data);
      Ans_10=str2num(Vehicle_Class);

      VehClass = Ans_10;
      Class9_data = all(VehClass == 9, :);
      count=count+1;
      state=get(handles.popupmenu1,'value');
      month(K)=unique(str2num(Month_of_Data));

      switch state
          case 1
              %         month(K)=unique(str2num(Month_of_Data));
              set(handles.push1,'Class9_data',Class9_data(Ans_7 == 1, :));

          case 2
              %         month(K)=unique(str2num(Month_of_Data));
              set(handles.push1,'Class9_data',Class9_data(Ans_7 == 7, :));
      end
  end

Dear Mr Walter, I solved this question and it was my mistake by not defining the proper tags for the controllers. Thank you man

Please help......

What is class(handles.PB2ON) and class(handles.PB2OFF) ?

I do not recall ever having encountered a Mathworks object class that had a property named variable

I wonder if you wanted to use 'visible' instead of 'variable', or if you wanted to use 'enable' instead of 'variable' ?
