There is a difference between the Value property and the String property. Also, you're better off using switch (which will make your code cleare), or a dictionary instead of a list of ifs.
function popupmenu1_Callback(hObject, eventdata, handles)
switch get(handles.popupmenu1,'Value');
case 1
set(handles.text2,'String',1000);
case 2
set(handles.text2,'String',1200);
case 3
set(handles.text2,'String',3000);
case 4
set(handles.text2,'String',4000);
end
Or with a dictionary:
function popupmenu1_Callback(hObject, eventdata, handles)
dict={1000,1200,3000,4000};
set(handles.text2,'String',dict(get(handles.popupmenu1,'Value')));
end
