What I am trying to do is SHOW a hidden div when the querystring variable Login = "Failed". So far I have got the variable value bit working and it is alerting that the value is "Failed" but actually showing the div is resulting in an error which is "Object required".

Do I need to add an event to the body dynamically in relation to the variable value and if so how do I do this?
HTML Page

--------------

<script language="javascript">

var qs = new Querystring()

var v1 = qs.get("Login");

alert(v1); //WORKS UP TO HERE

if(v1 == "Failed") {

	slidedown('mydiv');

}
 
 

JS FILE

--------------

var timerlen = 5;

var slideAniLen = 250;
 

var timerID = new Array();

var startTime = new Array();

var obj = new Array();

var endHeight = new Array();

var moving = new Array();

var dir = new Array();
 

function slidedown(objname){

        if(moving[objname])

                return;
 

        if(document.getElementById(objname).style.display != "none")

                return; // cannot slide down something that is already visible
 

        moving[objname] = true;

        dir[objname] = "down";

        startslide(objname);

}
 

function slideup(objname){

        if(moving[objname])

                return;
 

        if(document.getElementById(objname).style.display == "none")

                return; // cannot slide up something that is already hidden
 

        moving[objname] = true;

        dir[objname] = "up";

        startslide(objname);

}
 

function startslide(objname){

        obj[objname] = document.getElementById(objname);
 

        endHeight[objname] = parseInt(obj[objname].style.height);

        startTime[objname] = (new Date()).getTime();
 

        if(dir[objname] == "down"){

                obj[objname].style.height = "1px";

        }
 

        obj[objname].style.display = "block";
 

        timerID[objname] = setInterval('slidetick(\'' + objname + '\');',timerlen);

}
 

function slidetick(objname){

        var elapsed = (new Date()).getTime() - startTime[objname];
 

        if (elapsed > slideAniLen)

                endSlide(objname)

        else {

                var d =Math.round(elapsed / slideAniLen * endHeight[objname]);

                if(dir[objname] == "up")

                        d = endHeight[objname] - d;
 

                obj[objname].style.height = d + "px";

        }
 

        return;

}
 

function endSlide(objname){

        clearInterval(timerID[objname]);
 

        if(dir[objname] == "up")

                obj[objname].style.display = "none";
 

        obj[objname].style.height = endHeight[objname] + "px";
 

        delete(moving[objname]);

        delete(timerID[objname]);

        delete(startTime[objname]);

        delete(endHeight[objname]);

        delete(obj[objname]);

        delete(dir[objname]);
 

        return;

}
 

function toggleSlide(objname){

  if(document.getElementById(objname).style.display == "none"){

    // div is hidden, so let's slide down

    slidedown(objname);

  }else{

    // div is not hidden, so slide up

    slideup(objname);

  }

}

</script>
 

<body>

    <div id="mydiv" style="display:none; overflow:hidden; height:35px; width:920px; margin:0px auto; padding:0px 20px; background-color:#000; color:#fff;"> </div>

You need the div to exist so you have to wait until after load

<script language="text/javascript">

var qs = new Querystring()

var v1 = qs.get("Login");

alert(v1); //WORKS UP TO HERE

window.onload=function() {

  if(v1 == "Failed") {

    slidedown('mydiv');

  }

}

</script>
