[vicpal25]

AWRRGHH...WHY IS ISNT THE FOLLOWING FUNCTION RECOGNIZING THE FLOOR():

<script Language="JavaScript">


function formvalidation(){
var quantity=parseInt (document.paypalform.quantity.value)


if((document.paypalform.specialoffer.value == "yes") && (quantity == 2))
{
var discount=(20 * (floor(document.paypalform.quantity.value) / 2))
window.alert(discount)
}
else
{
window.alert("no it is not in offer")
}
}
</script>
