Deselect select box

Hey

I have a select box that allows a maximum of 4 selections before throwing an alert on screen.

What the function doesn't do , which I want it to is:

When the user ok's the alert, the last selected element stays highlighted. So the user is able to highlight another element, get the message again, but he now has 5 elements highlighted. I want the function to remove the last selected element when they get the alert.

Here is the code:

function CheckNum()" & _
{
var Counter = 0;
for (i=0; i<document.myform.theselectbox.length; i++)
{
if (document.myform.theselectbox[i].selected == true)
{
counter++;
}
}
if (Counter > 4)
{
alert(""Limit reached."");"
document.myform.theselectbox.value="""";
document.myform.theselectbox.focus;
return false;
}
}

I'm sure the answer is staring me in the face, but i'm a touch braindead at the moment and could use a fresh pair of eyes

No matter i've done it.

Can't believe i missed selected=false.

doh.
