getElementById problem in FF

[Frances Del Rio]

I am getting this error in Firefox.. what does this mean, pls? I have
never seen a JavaScript error like this..

Error: uncaught exception: [Exception... "Illegal operation on
WrappedNative prototype object" nsresult: "0x8057000c
(NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame ::
file:///C:/Documents%20and%20Settings/fdelrio/My%20Documents/cc/site/index.html#
:: chgLang :: line 43" data: no]
basically this is on a show-div/hide-div function to switch between two
languages..

line in question is: var div_top_lang = getElem(curr_div_lang);
(where getElem = document.getElementById)

url:

(function calls and functions all here..)

language-switch works fine in IE.. but not in FF... I have used
getElementById many times just in this way, as for ex. these two urls,
which both work fine in FF..

getElementById is a method of the document object and should be used as
such whereas your code unbinds the function from the document object by
assigning it to a variable and then calls it. That does not work and
causes that error message.
Use
document.getElementById(curr_div_lang)
or if you think you need to shorten that then you can create a variable e.g.
var doc = document
and then call
doc.getElementById(curr_div_lang)

my gosh Martin, I could have sworn I did try this (getting it out of
var..) and it hadn't worked, probably some other stupid error... thank
you so much!!
