ph = handles.YourPopup;
lh = handles.YourListbox;

selection_index = ph.Value;
if ~isempty(selection_index)
  user_chosen_folder = ph.String{selection_index};
  dinfo = dir(user_chosen_folder);
  dinfo([dinfo.isfolder]) = [];   %only want file names
  filenames = {dinfo.name};   %names of the files
  lh.String = filenames;      %put the names in the listbox
  drawnow()
end

Hi, thank you so much

what is selection index?

[Rik]

It is the Value of your popop menu, so it is the index of your selection in that popup menu. So if you have selected the second item it will be 2, if you selected the 5th item it will be 5, etc.

Why don't you try the code that Walter gave you? If you don't understand a function, try reading the documentation. You asked what a specific variable meant, I explained it. If you don't understand the explanation, please say so, because giving you a code example will not help explaining what that value means.
