Hi,

Can somebody help me. I'm quite new to Javascript and HTML and I'm having problems with the following code. What I'm trying to do is get a simple program that will work out the total charge. I just can't figure it out.

What it needs to do is work out the total charge for a customer, basically in the format shown, where the customer is charged a £3.00 delivery charge if the order value is under £25, nothing if over or equal to £25 and nothing again plus a free gift if it's equal to or over £100> I have become come completely stuck so bear with me if it looks a mess.

Can somebody please please help!!

Thanks in advance

Scott

Sorry, can't help with the javascript coding, but one idea might be to install a shopping cart that will handle this along with all the other stuff for online ordering. You can get many ready to go packages in perl or PHP that are easy to install and set up. Check out Google with 'php shopping cart' or 'cgi cart script'.

OS Commerce is free and full featured. Again sorry I cannot assist with code, good luck.

whoa syntax errors! lol

I've fixed part of it, with it you should be able to see what the problems were and fix the rest

Code:


<HTML>
<HEAD>
<TITLE>
Delivery charges
</TITLE>

</HEAD>
<BODY>
<SCRIPT type = "text/javascript">

var orderValue; // How much the order is worth
var deliverycharge;
var total;
orderValue=window.prompt("How much is the order worth in Pounds Sterling?");
document.write ('The value of your order is £' + orderValue + '.<br>');

orderValue = window.prompt('Please enter today\'s order value in Pounds Sterling', '');
orderValue = parseFloat(orderValue);
if (orderValue < 25)
{
deliverycharge =3;
total = orderValue + deliverycharge;
document.write('Delivery Charge is £3.00')
document.write("The total charge of " + orderValue + " and " + deliverycharge + " is " + total+ '.');

}
else //only a place holder so you can see that it went completed not died
{
document.write('Delivery Charge is £3.00')
}
</SCRIPT>
</BODY>
</HTML>
