how to call mfile function from gui?i have input image in one call back which i need to pass to the function in mfile....function call should be in another callback..

function pushbutton2_Callback(hObject, eventdata, handles)
ention(handles.A,S,S1,S2,S3,S4,S5,S6) ;

function pushbutton1_Callback(hObject, eventdata, handles)
[file path]=uigetfile('*.jpg','Select any image');
chosenfile=[path file];
handles.A=imread(chosenfile);
global img 
img=imread(chosenfile);
imshow(img);

%S values are values got from user using popmenu(7)
function popupmenu1_Callback(hObject, eventdata, handles)
global S
k= get(hObject,'String');
s=k{get(hObject,'Value')};
S=str2num(s);

i cant call my en function by passing those values along with img..i have also tried with handles.A or handles.S...

error is
 Reference to non-existent field 'A'.
