Hello,

I currently have the following js code

function clearMulti(option)
{
    var i;
    var select = document.getElementById(option.parentNode.id);
    for(i=1;i<select.options.length;i++)
         {
        select.options[i].selected=false;
    }
}

and

function clearAllOpt(select)
{
    select.options[0].selected = false;
}

The first one deselects all options in the multiple select when called and the second clears the first option whenever anything else is selected.

The need for this is that the first option is for All.

This all works fine and dandy in FF, but in IE8 nothing happens... any suggestions on how to get this to work in both?

Thanks in advance.
