Your advice is well taken. I have substituted my part of code which deals with reconfiguring the normal and disabled states of the back and next buttons. And It's working beautifully. The one thing I am still struggling with is tying my hash so that it displays in the original order of the data structure. It seems that the ordering only affects the keys of the hash of hashes not the element keys which store anonymous arrays. Any way around that? This is just beyond my poor human grasp. Thanks for all your help.
