I am trying to detect if the user has selected something from a multi drop
down box and also if they have selected just one item. I cannot get the JS
to detect it and to give me an alert. Can anyone look at the code below
and tell me what I am doing wrong?

ps...the brackets on the select box acct[] are needed so php will know how
to handle the variables on the next page.
JS
<script LANGUAGE="JavaScript">
function multiMeterCheck(form){
alert('1');
if(form.acct.options[form.acct.selectedIndex].text == ""){
alert('You must select atleast 2 meters.');
return(false);
}
alert('2');
}
</script>
Multi Select box
<form method="get" action="index.php" name="multi" onsubmit="return
multiMeterCheck(this)">
<input type="hidden" name="USID" value="87ab58294f2260a616ab8a57e21c9bed" />
