I've created a bear here with this little program. I need to include the below code in the existing working program. Can someone help?
// ****************************************************
var balance;
var stillowed;
balance = rentdue + prevbal + misc - hudpay;
stillowed = balance - amtpaid;
function isitlate(dayNow)
{
if(dayNow > 5){late = "L";
prevbal = stillowed + 10;
}
}
// **************************************************

<script>
function calculate_paid(v)
{
var amtpaid = document.getElementById("amtpaid");
var tentpay = document.getElementById("tentpay");
var hudpay = document.getElementById("hudpay");
var datepaid = document.getElementById("datepaid");
var late = document.getElementById("late");
var dateNow = new Date();
var dayNow = dateNow.getDate();
var datePaid = (dateNow.getMonth()+1)+"/"+dateNow.getDate()+"/"+dateNow.getFullYear();
switch(v)
{
case amtpaid:
var tpay = amtpaid.value - hudpay.value;
if(tpay >= 0){tentpay.value = tpay;}
if(amtpaid.value > 0){datepaid.value = datePaid;}
break;
case tentpay:
if(!hudpay.value || hudpay.value == " "){hudpay.value = 0;}
if(!tentpay.value || tentpay.value == " "){tentpay.value = 0;tentpay.select();}
amtpaid.value = parseInt(tentpay.value) + parseInt(hudpay.value);
if(tentpay.value > 0){datepaid.value = datePaid;}
break;
case hudpay:
if(!tentpay.value || tentpay.value == " "){tentpay.value = 0;}
if(!hudpay.value || hudpay.value == " "){hudpay.value = 0;hudpay.select();}
amtpaid.value = parseInt(tentpay.value) + parseInt(hudpay.value);
if(hudpay.value > 0){datepaid.value = datePaid;}
