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

I will check in my crystal ball, meanwhile post the code or share the files because my crystal ball might fail to get you an answer.

[Patrick]

I posted the code. Let me know what you think!

[Oleg Komarov]

Your code is incomplete and it way too long.

[Matt Fig]

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...

Answer 1

[Walter Roberson]

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

Answer 2

[Patrick]

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
