I have two list boxes (configured as combo boxes) A & B in a form. If the user changes the value in A I want to immediately change the value of B to match it. If it would be easier, I could change the second list box to be either a lable or text box. I don't use the value of the second box...it is there as a place keeper to make the form more understandable.
I added the code below to the On Change Client event. The code errors out when the page loads and, not knowing much about Java, I don't know why and the error code returned does not help.
<SCRIPT LANGUAGE="JavaScript">
function fillcombo(){
document.Courses.VideoB.options =
new Option(document.courses.VideoAB.options, document.courses.VideoAB.options);
}
</SCRIPT>
The page name is Courses_maint.asp
The form name is Courses
The first listbox is VideoAB
The second listbox is VideoB

Try setting IE to debug any errors in scripts:
Tools, Internet Options, Advanced tab, click to enable "Display a notification about every script error".
If you debug the error after such notification then you will know the error but also see the DOM structure of the page.
Unfortunately, after such a debug IE just crumples and will unload all of the IE sessions running.
If you wanted a better DOM structure examination of your pages try Mozilla www browser but you will then suffer from a poorer JavaScript implementation.
You will be amazed at how many script errors there are on the www.
Also hava a look at setting the Format/id value of your combo controls. Setting such an id will expose the combos at a simpler DOM level.
