Dynamic control variable access 1

Hello, i have a span im trying to display using javascript from a .net page, i have the click working to expand each item individually, but im trying to have an "Expand All" button. i get err style is null or not an object.

ive tried document.getElementByID(dlProducts...), but errs with Object doesnt support this.

any input would be super!

        for (var a=2; a < 5; a++) {
          dSpan = "dlProducts__ctl"+a+"_detailSpan";
          dSpan.style.display = 'block';
          dSpan.style.visibility = 'visible';
        }

heres the one that works individually

tr2.Attributes.Add("onclick", "showContact(" + sp1.ClientID + "," + img1.ClientID + ");");

function showContact(clicked,image)
{
var elem = clicked;
    if (elem) 
    {
        if (elem.style.display != 'block') 
        {
            elem.style.display = 'block';
            elem.style.visibility = 'visible';
            image.src = "img/action/plusout.gif";
        } 
        else
        {
            elem.style.display = 'none';
            elem.style.visibility = 'hidden';
            image.src = "img/action/plusin.gif";
        }
    }
}

use document.getElementByI[red]d[/red](clicked). notice the lowercase d.

HOLY!!!!!

thats what it was...
tossed in var total and null object handling...

function showAll(total)
{       
   for (var a=0; a < total; a++) 
    {
        var dSpan = "dlProducts__ctl"+a+"_detailSpan";
        dSpan = parent.document.getElementById(dSpan);
        if (dSpan){
            dSpan.style.display = 'block';
            dSpan.style.visibility = 'visible';
        }
    }
}
