The code (both this and after some minor adjustments) produced the proper
HTML (proved by viewing doc src). But doesn't display the default item
w/in the box. I added a scrolling_list and an HTML coded "popup_menu" and
both of those displayed properly. I will attempt to use the above two
codes and see any possible varience in resulting HTML. I'll update evryone
tonight. Thanks for your assitance.
