using the values in popup menu function in pushbutton_callback

Hi; I am doing GUI which has a popup menu that allow the user to choose from several options, lets say I have three options each one has different values for (I,V,P) current, voltage and power. my coding is like this (for example):

function popupmenu1_Callback(hObject, eventdata, handles)
  switch get(handles.popupmenu,'Value')   
    case 1
      I=7;
      V=20;
      p=130;
    case 2
      I=5;
      V=30;
      p=170;
    otherwise
 end

then I need to use these values in some calculation in pushbutton_callback, which it coding as below(for example):

function pushbutton1_Callback(hObject, eventdata, handles)

what code can I use to get these values from the popup menu ?? I need your help please.

Hi,

you have two options: either, the popupmenu1_Callback stores the values for I, V, p using e.g. guidata and the pushbutton1_Callback retrieves them. Add at the end of popupmenu_Callback:

handles.data.I = I;
handles.data.V = V;
handles.data.p = p;
guidata(hObject, handles);

and in the pushbutton1_Callback use them:

I = handles.data.I;

Alternative: move the code you've written in popupmenu1_Callback to pushbutton1_Callback, i.e., when you click the pushbutton, the value from the popupmenu is read and the values computed.

I couldn't find such function in my code ?

I have tried your both ways, and non of it is working. I can't get the values in push-button.
