GUI Push Button Behavior

I have a push button which, when pressed, uses the uigetdir function to get a directory. However, when I press it again, I get an error:
??? Undefined function or method 'Program' for input arguments of type
'struct'.
Error in ==>
@(hObject,eventdata)Program('load_Callback',hObject,eventdata,guidata(hObject))
??? Error while evaluating uicontrol Callback
I want it to simply reopen the uigetdir dialog and load a new directory, if pressed again.

Does "Program" try to call another function called "Prpgram"??? Maybe it's just a spelling mistake. What is the tag property of your pushbutton? Is the button called load? Set a breakpoint in the callback. Does it ever get there when you click the button? Do you know how to use the debugger? This would be fairly simple if you did.

cd() should not be necessary - I rarely use it. uigetdir() will work just fine without calling cd(). However if you pass a directory to uigetdir(), you should use exist(folder, 'dir') first to make sure the directory exists.
