in short, you can't.

you need javascript so I will move this to the client side forum.

well you would need to do it javascript as said before. DO you know anything at all about javascript?

heres the basics behind it

<script type="javascript">
var shipping = 50;
var handling = 30;
var discount = 10;

total = shipping + handling - discount;
</scrip>


but the problem is filling these values with different values, how are you doing your page?

You will need to replace "= 50"
with "= [some argument]" where [some argument] means some kind of code that retrieved the correct price.
