pop up activation with push button

Hi guys, please help!

I have created two pop up menus (in GUI over guide), and I want to create plot (filter type) based on the user selection. This plot should be created by push button.

I have made following code (bellow), but it doesn't work, even though there are no errors reported.

function prikazfitra_Callback(hObject, eventdata, handles)

u = get(handles.filterMenu,'value'); %get currently selected option from menu
v = get(handles.vrstafiltMenu,'value'); %get currently selected option from menu

if u == 2 && v == 1
    d=str2double(get(handles.d,'string'));
    r=str2double(get(handles.r,'string'));
    
    Wn=2*d/handles.fs;
    b=fir1(r,Wn);
    
    % plot frekvencijskog odziva filtra
    axes(handles.grafik2);
    plot(b,1:length(b)); grid;
    freqz(b,1);

elseif u == 2 && v == 2
   %stuff here
elseif  u == 2 && v == 3
   %stuff here
elseif  u == 2 && v == 4
   %stuff here
elseif  u == 3 && v == 1
   %stuff here
elseif u == 3 && v == 2
   %stuff here
elseif u == 3 && v == 3
   %stuff here
elseif u == 3 && v == 4
   %stuff here
end

not all elseif are shown. u and v are selections from pop up menu. d and r are edit with number value.

Thanks!

I recommend using the debugger to trace the execution.
