adding things up

[AshleyH]

Hi Everyone

I have this code:

 <script language="JavaScript">
 var one=0;
 var two=0;

 function myCalc() {

 one=Math.abs(parseFloat(document.FORM.one.value));
 two=Math.abs(parseFloat(document.FORM.two.value));

 document.FORM.two.value=(one*12.99);

 }
 </script>

which simply multiplies 'one' by 12.99.

I need to have it so if the number is more than 1 in 'one' it add's 12.99 and then and only adds 6.50 for every other number more than 1.

Basically what I want it to do is work out a figure if you buy 1 you get the others at half price.

Is this doable with this script?

Many thanks

Hmm. Are you using any server-side language for this? I wouldn't rely on Javascript for this (since it can be disabled).

Hi,

Thanks for getting back to me.

I'm using Coldfusion with it.

var two = (one > 0) ? (12.99 + ((one-1) * 6.99)) : 0;

If one is 1, then you'll get 12.99
If one is more than 1, you'll get one at 12.99 and the rest at 6.99
If one is 0 or less (or not a number) then you'll get 0

Also you might want to use parseInt() instead of parseFloat(). ParseInt will convert decimal numbers (10.25, for example) to integers (10). You probably won't selling .25 of something.
