Get value of a variable from one popupmenu1 function and use it in different popmenu2 function

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; 
end

function popupmenu2_Callback(hObject, eventdata, handles)

[In this function, I want to use the value of x.]

You cannot do that as-is. "x" is local to the workspace of popupmenu1_Callback and will disappear as soon as that callback finishes. You need to save the value of x in a place that the other callback can get at it.

Thanx Walter for your reply. But I found out the solution. Here is the code, may be helpful for you.

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
