How to validate this kind of dropdown list? (on form submit)
The first list is empty...An alert message will popup if the list selected is empty...

<select name="bnRoom">
<option></option>
<option>MONDAY</option>
<option>TUESDAY</option>
<option>WEDNESDAY</option>
<option>THURSDAY</option>
<option>FRIDAY</option>
</select>

Heres how using javascript, you haven't given the elements any values so i have added them in, and there is no reason to put a blank item in your select.

<html>
<head>
<title>Untitled Document</title>
<script language="javascript">
function fCheck(val1){
if (val1 == ""){
alert("Please select a value");
return false
}else{
return true
}
}
</script>
</head>

<body>
<form action="http://www.mcfc.co.uk" method="post" onSubmit="return fCheck(bnRoom.value);">
<select name="bnRoom">
<option></option>
<option value="MONDAY">MONDAY</option>
<option value="TUESDAY">TUESDAY</option>
<option value="MONDAY">WEDNESDAY</option>
<option value="THURSDAY">THURSDAY</option>
<option value="FRIDAY">FRIDAY</option>
</select >
<input type="submit" value="click me!">
</form>
</body>
</html>
