How to call the output from gui button?

Hello, here is my code

function load_data_Callback(~, ~, handles)
% hObject    handle to load_data (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

[filename, pathname] = uigetfile('*.mat','Load Image');
if filename == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(pathname, filename);

storedata1 = load(fullFileName);
combineFIX=storedata1.combineFIX;

set(handles.edit20,'String',[pathname filename]);
set(handles.text13,'String','it works!');

and also here

function pushbutton22_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton22 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

[filename, pathname] = uigetfile('*.mat','Load Image');
if filename == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(pathname, filename);

storedata2 = load(fullFileName);
labels=storedata2.labels;
combineFIX=handles.combineFIX;  %i try to call combineFIX from the button above,but it can't works
result_function; % a function that has labels and combineFIX as its input 
set(handles.edit23,'String',[pathname filename]);
set(handles.text16,'String','numInst');  %numInst is the output of result_function

so, i want to call the combineFIX in the second button then do result_function and result numInst as its output. What should i do? thanks in advance.

anyone can help me,please

What does "call the combineFIX" mean? What is "combineFIX" and what does "can't work" exactly mean?

I do not understand this also:

 result_function; % a function that has labels and combineFIX as its input

No, result_function does not have any inputs.

[Tara]

combineFIX is a variable from .mat file in the load_data, and labels is a variable from .mat file in the pushbutton22. sorry, i mean result_function isn't a function, but it is M file, result_function.m that has variable combineFIX and labels. to display numInst from that result_function, i need combineFIX and also labels. so, how can i display the numInst from the pushbutton22?

If result_function is an M-file, but not a function, it must be a script. Inside the script you cann access all variables of the caller. In your case, labels and combineFIX can be used directly. So what is the problem?

Perhaps you should convert result_function to a function (then the name would be less confusing). Add this line on top:

function numInst = result_function(labels, combineFIX)
...

Then you have defined inputs and outputs.

my code doesn't work. it says

??? Reference to non-existent field 'combineFIX'.
