"directory" is a variable in your code. Use dir.
help dir

At this point you want d = dir;

Along the same lines, is there a way you can add an
additional option to the list at the bottom, like 'Create
new' or something like that? Or can you only list the
directory files?

Add a line before the set() call:

filenames{end+1} = 'Create New';

I think you will find, though, that the code is easier to
write and maintain if you make the 'Create New' the *first*
entry in the list rather than the *last* entry in the list.

Thank you very much! That did the trick.
