How to use the same variable in different functions in GUI MATLAB

I have a popup menu with the following code. There are two options as C1 and C2. If the user selects C1, I want to set the value as 10 and if the user selcts C2, I want to set the value as 20.
function pop_Callback(hObject, eventdata, handles)
contents = cellstr(get(hobject,'String'));
A = contents{get(hObject,'Value')};
if (strcmp(A,'C1'))
X = 10;
elseif (strcmp(A,'C2'))
X = 20;
end
set(handles.pop,X)
I want to use another function with a pushbutton and static text to display the answer, where the output is, Whatever the set value + 12.
function push_Callback(hObject, eventdata, handles)
inX = get(handles.pop,X);
out = inX;
set(handles.ans,'String',out)
However, I have some error in set and get function.

At the end of a callback handles is not stored automatically, or somehow passed to other callbacks/functions. You have to do this explicitly, by calling guidata at the end of the callback:
guidata(hObject,handles)
Only then can you get .pop in the other callback. See the examples in the documentation:
href = ""</a>
