Fade in / out and create / hide <DIV> using javascript

Question

I create some of them at runtime. For this, I use this function:

function creatediv(id, html, left, top) {

if (document.getElementById(id)) 
    {
        document.getElementById(id).style.display='block';
        fadeIn(id, 300);
    }
    else
    {
        var newdiv = document.createElement('div');
        newdiv.setAttribute('id', id);
        newdiv.setAttribute("class", "warningDiv"); 
        newdiv.style.position = "absolute";
        newdiv.innerHTML = html  + '<h1>(click to close)</h1>';
        newdiv.style.left = left;
        newdiv.style.top = top;
        newdiv.onclick=function(e) {
            fadeOutAndHide(id, 300);
        };  
        document.body.appendChild(newdiv);
        fadeIn(id, 300);
    }

} 

This function does not work with IE, and I do not know why. I see no errors with this javascript. These are the fade-in functions:

function fadeOutAndHide (id,millisec)
{
    var object = document.getElementById(id).style;
    var opacStart = 100;
    var opacEnd=0;
    var speed = Math.round(millisec / 100);
    var timer = 0;

    for(i = opacStart; i >= opacEnd; i--) {
        setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
        timer++;
    } 

    var elemento = document.getElementById(id);
    if (opacEnd==0){
    elemento.style.display='none';
    }
}


function opacity(id, opacStart, opacEnd, millisec) {
    var speed = Math.round(millisec / 100);
    var timer = 0;

    if(opacStart > opacEnd) {
        for(i = opacStart; i >= opacEnd; i--) {
            setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
            timer++;
        }
    } else if(opacStart < opacEnd) {
        for(i = opacStart; i <= opacEnd; i++)
            {
            setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
            timer++;
        }
    }
} 

Another problem I have: the fadeout function is not working properly. The div disappears, but the click event fires when the div is hidden. This is the fadeout function:

function fadeOutAndHide (id,millisec)
{
    var object = document.getElementById(id).style;
    var opacStart = 100;
    var opacEnd=0;
    var speed = Math.round(millisec / 100);
    var timer = 0;

    for(i = opacStart; i >= opacEnd; i--) {
        setTimeout("changeOpac(" + i + ",'" + id + "')",(timer * speed));
        timer++;

    } 

    var elemento = document.getElementById(id);
    if (i==1){
    elemento.style.display='none';
    }
}

So what can I do to fix these problems?

thanks
