SELECT options is null or not an object

I think that's a JavaScript error message, no?... In a popup window rather
than in the middle of your page...

Ah, yes.
*Here* you try to dig down into the form object to get your DocID:
> var docID = list.options[list.selectedIndex].value;
And *here* you also try to dig down into the form object to get your DocID:
> onChange=\"getDocID(this.options[this.selectedIndex].value)\" SIZE=5>\n";
You should only be doing all that this.options[this.selectedIndex].value in
*one* of the two places.
I'd put it in the function, myself. YMMV. It's a religious issue.
