Try this:
<script>
function checkYear() {
var frm = document.forms[0];
if (parseInt(frm.YearFrom[frm.YearFrom.selectedIndex].value) >
parseInt(frm.YearTo[frm.YearTo.selectedIndex].value)) {
alert("Your From Date must be less than your To Date.");
}
}
</script>

Hi,
Could anyone give me advice on the following function?
Ive got 2 Select boxes with Years as the value for each,so that the user
can pick dates from to etc.
ie From <select name="YearFrom"> 1999 up to 2030
to <select name="YearTo">1999 up to 2030
what i require is a function (Onsubmit) that makes sure that the year
to is not less than the year from,throwing up an alert box.
Many Thanks in Advance
