Hello all, I have a javascript error on one of my pages in my webChat ASP app. When i load up the page, In the frame that contains the page where all the users are listed, I get an error abour an HTML element on my page () being null or not an object, but it works anyway. Here is my code, (located on an ASP page):

function loadListOfUsers()
{
var currentUsers = '<%=Application("users")%>';
var userList = "";
var noOfUsers = 0;
if (currentUsers != "" && currentUsers != null && currentUsers.length > 0)
{
currentUsers = currentUsers.split("|");
for (i = 1; i < currentUsers.length; i++)
{
if (currentUsers[i] != " " && currentUsers[i] != "")
{
userList += currentUsers[i] + "
";
noOfUsers++;
}
}
noOfUsers = (noOfUsers < 2) ? noOfUsers + " person in room." : noOfUsers + " people in room.";
window.noOfUsers.innerHTML = noOfUsers;
window.roomPeopleList.value = userList;
}
else
{
window.roomPeopleList.value = "Unable to
find any
users in
this room."
}
}

function returnTheFormattedTime()
{
var date = new Date();
var date_hours = date.getHours();
var date_minutes = date.getMinutes();
var date_seconds = date.getSeconds();
var AM_PM = (date_hours < 12) ? "AM" : "PM";
if (date_minutes <= 9) date_minutes = "0" + date_minutes;
if (date_seconds <= 9) date_seconds = "0" + date_seconds;
date_hours = (date_hours > 12) ? date_hours - 12 : date_hours;
return date_hours + ":" + date_minutes + ":" + date_seconds + " " + AM_PM;
}

function renewDefaultStatusValue()
{
window.defaultStatus = 'LOGGED IN: <%=Session("uName")%>. TIME: ' + returnTheFormattedTime();
window.setTimeout('renewDefaultStatusValue()', 1000);
}

loadListOfUsers();
renewDefaultStatusValue();

    Hi

    Try replacing : "window.noOfUsers.innerHTML = noOfUsers;"
    for "window.document.getElementById(noOfUsers).innerHTML = noOfUsers;",
    "window.roomPeopleList.value = userList;" for
    "window.document.getElementById(roomPeopleList).value = userList;" and
    "window.roomPeopleList.value = "Unable to
    find any
    users in
    this room."" for "window.document.getElementById(roomPeopleList).value = "Unable to
    find any
    users in
    this room."".

    Hope this help.
