Hi Plemon,

There are a few things causing trouble.

If you are going to use a doctype (which is good to do) then it is a
good idea to also validate you markup. <URL: http://validator.w3.org/>

If you want to use if-else blocks with multiple lines in each case then
you want to use braces around the mutiple lines with each case.

You can only use document.write while the page loads. After the page
loads you use different techniques to manipulate the page.

Strings need to be in either double or single quotation marks.

The following works but it isn't the prettiest.

May I suggest <URL: http://jibbering.com/faq/#FAQ3_1> to get you going
faster if you are interested in learning JavaScript.

I would try to make it a little simpler by making 2 small changes.
1) Change function f1 to accept arguments you want to set vars to.
the function would look like this:
function f1(theButton,a,b,c,d){
if (theButton.checked){
var v11 = a;
var v12 = b;
var v13 = c;
var v14 = d;
}
}
2)Change the input tags so you pass the radio button (this) to the function
as well as the other values..
<input type="radio" name="rb1" value="799.97" checked="checked" onclick
= "f1(this,0,25,75,100)">
<input type="radio" name="rb1" value="799.97" onclick =
"f1(this,25,0,25,50)">
<input type="radio" name="rb1" value="799.97" onclick =
"f1(this,50,25,0,25)">
<input type="radio" name="rb1" value="799.97" onclick =
"f1(this,75,50,25,0)">

Also I would leave the dollar sign and other formatting off untill you
display it in case you want to perform any math with the values.

yeah i like the second response a lot although the first works i can
work the second one to my needs with less hassle and about adding them
up im going to change the values and add the values of the checked ones
instead of the variables or i will pass each value into a var and then
add the vars

You'll find that you get more and better responses if it's easier
to ready what you post. Use standard punctuation and capitalization.
This isn't a chat room.

The "shortcut" property accessors of referencing a named form as a named
property of the document, and referencing a named form control as a
property of the FORM element should not be expected to be available in
XHTML DOMs. If you are going to script a DOM in a way based upon the
assumption that it will be an HTML DOM that is being scripted it makes
more sense to mark-up the document in a way that is unambiguously HTML,
not XHTML.

Richard.
