Push Button on a GUI problems

I am making a GUI with 3 push buttons. Everything works fine, push buttons included. But after I press the push buttons a total of 8 times (it does not matter in which order I press them), they stop working. Can someone help me? I would really appreciate it.
Thanks

Your code is incomplete and it way too long.

750 lines as pasted. I would like to help, but that is just way too much to wade through. I suggest you narrow it down as much as you can, then re-post...

3 buttons, 2^3 possible states, code fails after pressing 2^3 times...

Wow, that came out bad, but I'll just repost the part of the code with the push buttons and the functions that they call.
Push Button 1:
function startButton_Callback(hObject, eventdata, handles) % hObject handle to startButton (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) start=get(handles.playerMenu,'Value'); %Gets player information venue=get(handles.venueMenu,'Value'); %Gets venue information
if start==1 && venue==1
msgbox('Please select a player and venue!')
elseif start==1
msgbox('Please select a player!')
elseif venue==1
msgbox('Please select a venue!')
else
iVenue=get(handles.venueMenu,'Value');
switch iVenue
case 2
axes(handles.gamesAxes);
img=imread('joycebckgrnd.jpeg');
imagesc([0 27], [-2 17],img);
set(gca,'YDir','normal')
set(handles.gamesAxes,'XTick',[])
set(handles.gamesAxes,'YTick',[])
case 3
axes(handles.gamesAxes);
img=imread('ruckerbckgrnd.jpeg');
imagesc([0 27], [-2 17],img);
set(gca,'YDir','normal')
set(handles.gamesAxes,'XTick',[])
set(handles.gamesAxes,'YTick',[])
end
hold on
x=randi(21); %Generates random location for ball
a=get(handles.feetText,'String');
anum=str2double(a);
b=get(handles.inchesText,'String');
bn=str2double(b);

hold on
