Manipulating a link (hide/show) on form load

[Anonymous]

Following does not work. I would appreciate anybody helping me on this.

function onLoad ()
{
if (document.frm.exists.checked==true)
            document.getElementById   ("template").style.visibility =
                      "visible"
         else
            document.getElementById ("template").style.visibility = "hidden"
}

thanks,

Laxman
