Dariusz:
3-4 times you say?  Well, in that case the archives really are a better
solution for either of us.  I *will* pay more attention in the future. ;)

Oh, and... I just realized my puzzle was not quite solvable (read:
poorly constructed).  But I'll have other, better ones soon enough.  :)

Thanks for your input.
