I can GUARANTEE this will *NOT* work.
You *CANNOT* use [] as part of a 'name' in JavaScript.
No way, no how.
No matter how you quote it, embed it in a string, or try to sneak up on it.
It ain't gonna work.
'Cuz I tried every godamn reasonable (and quite a few UN-resaonable) ways
to do that. *
You'll just have to "know" that elements[7] is the one that you want.
Or maybe use an ID="xxx" attribute that does NOT have [] in it. But that
new-fangled ID attiribute was added long after I worried about this issue,
so you're on your own for that.
* In retrospect, you could probably write some kind of JavaScript function
that iterates through every single element, and compares its '.name' to
'distID' and to '3' (assuming you use distID[3] for a name) and then
return the one object you were looking for... But that would be horribly
inefficient JavaScript and would make your page dog-slow, so don't do
that.
