Oh I forgot...... for drop down list you need to change
this line of code
<option value="selected">SELECT</option> to this
<option value="0"SELECTED>SELECT</option>
And to validate would be something like this

function validateRating(form)
{
	var Rating = 1;

	if (form.Number.selectedIndex == 0) 
                {
		alert("Please select a rating");
		Rating = 0;
	}

	if (Rating) {
		form.submit();
	}
}
