Works in IE but not Nescape

[junai3]

I have this code I've written which works perfectly in Internet Explorer, but will not work in Netscape. I know Netscape requires better coding practices then IE, but I can't seem to figure out what's wrong with my code.

Here is my code:
-------------------------------------------------------

function TicketCost()
{
var CostPerTicket = 129;
var NumOfTickets;
var TotalCost;
var date;

NumOfTickets = Number(frmTickets.txtQuantity.value);

TotalCost = NumOfTickets * CostPerTicket;

var CostPerTicketChild = 89;
var NumOfTicketsChild;
var TotalCostChild;

NumOfTicketsChild = Number(frmTickets.txtQuantityChild.value);

TotalCostChild = NumOfTicketsChild * CostPerTicketChild;

frmTickets.txtCostTotal.value = TotalCostChild + TotalCost;

frmTickets.At_Least_1_Passenger.value = NumOfTickets + NumOfTicketsChild;

var Money = 10;
var discountPrice;
var Discount;
var subTotal;
var Passengers;
var noTax;
var Tax = 0.04166;
var withTax;
var result;

subTotal = Number(frmTickets.txtCostTotal.value);
Passengers = Number(frmTickets.At_Least_1_Passenger.value);
discountPrice = Passengers * Money;
Discount = subTotal - discountPrice;
withTax = Discount * Tax;
result=Math.round(withTax*100)/100;

PassengersM = Number(frmTickets.At_Least_1_Passenger.value);

frmTickets.txtDiscountTotal.value = Discount + result;
frmTickets.txtTaxTotal.value = result;
frmTickets.txtDiscountPrior.value = discountPrice;

}

-------------------------------------------------------

I call the code from a form where onChange and on Submit, it calls the function TicketCost(). Can anyone see what the problem is? I aprreciate the help.

I imagine it is the reference to "frmTickets" that's doing it. You're not defining it anywhere. Try adding this to the top of your function:

var frmTickets = document.forms['frmTickets'];

Hope this helps,

To the very top of my function, I added:

var frmTickets = document.forms['frmTickets'];

and most everything worked! Thanks a bunch. I can't believe I missed that. I also found that I didn't define "At_Least_1_Passenger", so I added:

var At_Least_1_Passenger

and now everything works perfectly.
