Dean, this is not a javascript list.  Please find one, it will be more

Try to keep things simple where you can.  Here's an example where I walk
through a form's elements to remove all selections in all select elements
except for the one select element that was passed into the function (this is
really part of a larger function) - it's not fully generic because the form
name "f1" is coded in, but obviously it would be easy to fix that:

function clearMost(select){//"select" is a select object
    var els=document.f1.elements,e,el//f1 is the name of a form
    for (e=0;e<els.length;e++){
        el=els[e]
        // the type of select elements starts with "select"
        if (el!=select&&el.type.indexOf('select')==0){
            el.selectedIndex=-1
        }
    }
}

if a select element is named "s1", in form "f1", you could call it like
this:

clearMost(document.f1.s1)

You should be able to do something very much like this.
