problem implementing the listbox directory in my GUI

I took the example of a listbox directory from the help and inserted it into my custom GUI so I can select from files to process. Works fine the first time I double click to change directory or select file, but then after that it causes all uicontrols to throw an error when clicked: undefined function or method 'myGui' for input arguments of type struct.

Any ideas why it would work fine first time and not again? For example if I use the listbox to change directories, it works, then every click after that throws the error.

Your function myGui needs to be on your MATLAB path or else it will not be found after you change directories.

Ahhh - I feel dumb. Thanks!

Well, you are not alone, I spent over an hour trying to figure out this identical problem before finding this answer. Thanks Walter!
