Hi there I am trying to link two guis together , I have successfully transfered data between them using setappdata and getappdata But I've got error when trying set data into table (Reference to nonexistent field)

function results_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to results (see VARARGIN)
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
a= getappdata(0,'a');
b=getappdata(0,'b');
d=zeros(size(a,1),size(b,2));
set(handles.uitable1,'Data',d)
choice=getappdata(0,'choice');
switch choice
    case 1
        if size(a)==size(b)
            r=a+b;
            set(handles.uitable1,'Data',r)
        else
           set(handles.text1,'string','lenghts must agree')
        end
    case 2
        if size(a)==size(b)
            r=a-b;
            set(handles.uitable1,'Data',r)
        else
           set(handles.text1,'string','lenghts must agree')
        end
    case 3
        if size(a,2)==size(b,1)
            r=a*b;
            set(handles.uitable1,'Data',r)
        else
           set(handles.text1,'string','inner dimensions must agree')
        end
    case 4
        set(handles.uitable1,'Data',inv(a))
    case 5
end
