GUI to plot sine and cosine given amplitude and frequency

My intention is to generate a GUI in Matlab in order to plot sine and cosine (chosen by a popup menu from user) while taking the values for amplitude and frequency from edittext inputs.
My GUI code shown below, can easily plot sine (or even cosine). However, it seems as if I have a problem making the popupmenu working correctly.
I realize this sounds very basic for actual GUI users, but it is essential for me to learn by making these simple cases work. any help is greatly appreciated.

Here is a link to my Matlab Script which plots but its popupmenu has problem:

you have just to program you puchbutton callback
function pushbutton1_Callback(hObject, eventdata, handles)
% when the button plot is pushed
f = str2num(get(handles.edit1,'String')); %geting f
A = str2num(get(handles.edit2,'String')); % geting A
t = 1:100
sine = A* sin(0.02*pi*f*t);
cosine = A * cos(0.02*pi*f*t);
val =double(get(handles.popupmenu1,'Value')); %geting popupmenu value(1 or 2)
if val==1
plot(sine);
else
plot(cosine)
end
