   Oh Anton you darling that looks like the ticket!! (The /id/ tags). I 
don't know how to use it yet but now I have something to work towards 
that looks like what I am already doing with the 'file_parent_dir' 
value!! Woohoo! I don't mind learning when I have an idea of -what- to 
learn (which until now I didn't - hence my frustration and desperation!)

Thank you very much!!

Madison

PS - I will let you know when it is ready!!
