Hello All, I am working on a GUI where I want to take input from user and use the variable in another function which is in a separate .m file.

I tried defining the variable as global but still the file where I want to call the value returns "undefined" error.

selection = get(hObject, 'Value');
switch selection
    case 1
        M2.h=msgbox('Please select the value');
    case 2
        M2.x2=1;
    case 3
        M2.x2=2;
    case 4
        M2.x2=3;
        prompt = {'Value1','Value2'};
        dlg_title = 'Properties';
        num_lines = 1;
        defaultans = {'',''};
        answer = inputdlg(prompt,dlg_title,num_lines,defaultans);
        M2.Value1=str2num(answer{1});
        M2.Value2=str2num(answer{2});
end      
set(handles.value_type, 'UserData', M2);

Now I want to call the Value1, Value2 in a separate .m file which runs in the script where above code is. Meaning the above code is a part of GUI which calls the functions from the another m file where I want the above input to be used.
