Try to set the ojbect of document.getEle mentById with a veriabled failes in FF

[Big Guy 60]

I can get this code to work in IE but not in firefox.

I have a site with 20 <div> item throughtout the site. All of the <div> tags have unique ids.

I am using an ajax call to hit a "heartbeat" page the returns a list of id names that I need to update the DIV contents.

Once the heartbeat runs this function is called.

function updateusage()
{
     if (document.getElementById('HeartBeatDIV').innerHTML != '') 
      {
         var updateinfodata = document.getElementById('HeartBeatDIV').innerHTML;
        updateinfo = updateinfodata.split(',');
     for(var i=0; i<updateinfo.length; i++){
         var brickInQuestion = updateinfo[i];
        var updateitembrick = document.getElementById(brickInQuestion);
        updateitembrick.innerHTML = tempcontent;
        updateitembrick.className  = 'brick_bought';
        updateitembrick.onclick = function() {donothing()};
        if (updateitembrick.style.backgroundColor != "") {
            removebrick(brickInQuestion);
            updateitembrick.style.backgroundColor = '';
            document.getElementById('selectedbricks').innerHTML = bricksSelected;
            document.getElementById('BrickDonation').innerHTML = brickdonation;
            }
        }
     }
 
}

The issue is that I am seeing in the Firebug debbuging tool is

updateitembrick has no properties
[Break on this error] updateitembrick .innerHTML = tempcontent;

This works perfectly in IE but not in FF. If I change the way I am setting the updateitembrick from

var updateitembrick = document.getElementById(brickInQuestion);

or

var updateitembrick = document.getElementById('brick_1');

then FF works fine.

I am not sure what I ma missing here

Welcome to TSDN!

Show the code for HeartBeatDIV.

Did you know that you could specify a language in the code tags, e.g. [code=javascript]?

The Hearbeat is a jquery script that returns a comma dilimated list of ids to a hidden DIV id "HeartBeatD IV"

a sample of the returned data is
brick_17,brick_ 1,brick_3
