I am very new to javascript and web programming. I have done some basic
pages using CGIDEV2 to build the pages, but, this is my first real foray
into ajax and extensive javascript. I did look at EXTJS, but my limited
(read none) knowledge of javascript made it hard to understand how to use.
I will look into DOJO, EXTJS and PROTTYPEJS further.  I did try a demo of
Valence which uses EXTJS, and returns JASON, and ti was much easier to
work with, compared to coding by hand.

Since there is no budget for software, and the update sounded simple I
thought I'd learn some javascript and learn how AJAX works. Now I know its
more IE then my code. As i said I was basing it on Aaron Bartell's article
in IBM systems mag, adn was able to duplicate his sample in my own
program. Being a green screen coder I didn't know it was not available in
IE to just replace the options and not the whole select group. Thanks for
that very important piece of information.

You can't get there from here. It's a known issue that you cannot set
the innerHtml on a select in IE and have it do what you want. Like it?
Nope. But there it is, deal with it. :-)

Options:

1 (Recommended): Return the <select> part too from the Ajax call and
wrap the select in a span and set the span's innerHtml, works fine.

2: Return just the <option> part, and wrap it up in a select in JS and
then see option #1.

3: Return the items you want in JSON, or other non-html format, and use
the .Add method to add the options to the select tag

Also... Why on earth are you not using a toolkit? If you take option 1
(my recommendation) and had prototype.js as your toolkit your entire
code could (from the <script> to the </script>) be replaced with:

function updDropDown(fldName) {
 Ajax.Updater('shiptospan',
  '/cgi-bro/SYG930?DDMODE=S&DDVIEWNAME=CB01HP&DDFLDNAME=BTCD&DDDEFAULT='
  + $F('fldName'));
}

where 'shiptpspan' is the id of the span you wrap the shipto select in,
and it would be x-browser to boot.
