Hi; I am doing GUI which has two popup menu functions. I defined the value of a variable x in popupmenu1 function. and want to use the value of x in popupmenu2. plz anybody tell me how can i use this?? For example->

function popupmenu1_Callback(hObject, eventdata, handles)
b=get(handles.popupmenu1, 'value'); 
switch b 
    case 1 
            x=0:.1:1; 
    case 2 
            x=0:.1:10; 
    case 3 
            x=0:.1:100;

You can use guidata

function popupmenu1_Callback(hObject, eventdata, handles)
b=get(handles.popupmenu1, 'value'); 
switch b 
  case 1 
    x=0:.1:1; 
  case 2 
    x=0:.1:10; 
  case 3 
    x=0:.1:100; 
end
handles.x=x
guidata(hObject,handles)

In the second callback

function popupmenu2_Callback(hObject, eventdata, handles)
x=handles.x
