Form not updateding when I click radio button.
I'm trying to change some text in a form when I click a radio button, but it isnt working, I know the javascript is wrong, because this is the first tiem I have tried implementing it, but I just cant find what is wrong with it. Here is the javascript function
Here is the form I am trying to update
and here is the radio button thing
I probably either did something wrong with the function, or I cant echo a PHP variable into the onclick, like you can echo variables into HTML Thanks in advance for any help, because this has been bugging me all day.

You should check for this.checked instead of this.check.
Btw, here's a quick way to do the if-else statement with variable assignment:
The syntax is simply:
variable = expression ? set_if_true : set_if_false ;
This syntax can also be nested like if - else if - else statements if needed.
Echoing into JavaScript should be no problems, as long as you add quotation marks to make JS interpret it as a string.

Thanks for that, sorry I didnt reply sooner, but I've been playing with it trying to make it work, but I just cant get it to work at all, so here is the code of the entire page, incase maybe the order of things are screwed up, or I have something named wrong Im not realizing.
PHP Code:
<?
include '../includes/header.php' ;
?>
<html>
<? include '../includes/meta_css.htm' ; ?>
<? include '../includes/banner.php' ; ?> " width="780" height="120" alt="Space Baron Banner" align="left"></td>
<? include '../includes/left.php' ; ?>
</td>
<?
if( $error != '0' )
"<p> $error </p><br>" ;
$name = $_SESSION [ 's_name' ];
//Functions
include "../includes/ship_func.php" ;
//Class
$class1 = class_s ( $class1 );
$class2 = class_s ( $class2 );
$class3 = class_s ( $class3 );
$class4 = class_s ( $class4 );
$class5 = class_s ( $class5 );
$class6 = class_s ( $class6 );
$class7 = class_s ( $class7 );
$class8 = class_s ( $class8 );
//Armor
$armor1 = h_armor ( $class1 , $armor1 );
$armor2 = h_armor ( $class2 , $armor2 );
$armor3 = h_armor ( $class3 , $armor3 );
$armor4 = h_armor ( $class4 , $armor4 );
$armor5 = h_armor ( $class5 , $armor5 );
$armor6 = h_armor ( $class6 , $armor6 );
$armor7 = h_armor ( $class7 , $armor7 );
$armor8 = h_armor ( $class8 , $armor8 );
//Weight
$weight1 = weight ( $class1 , $weight1 );
$weight2 = weight ( $class2 , $weight2 );
$weight3 = weight ( $class3 , $weight3 );
$weight4 = weight ( $class4 , $weight4 );
$weight5 = weight ( $class5 , $weight5 );
$weight6 = weight ( $class6 , $weight6 );
$weight7 = weight ( $class7 , $weight7 );
$weight8 = weight ( $class8 , $weight8 );
//Cost
$cost1 = s_cost ( $weight1 , $armor1 , $cost1 );
$cost2 = s_cost ( $weight2 , $armor2 , $cost2 );
$cost3 = s_cost ( $weight3 , $armor3 , $cost3 );
$cost4 = s_cost ( $weight4 , $armor4 , $cost4 );

How will arrays help me with my javascript problem? I know that I should be using arrays for all of the repeditive variables I generate with PHP. I just havent got around to it yet, but I'm trying to find out what's wrong with the javascript stuff.

It seems that the JavaScript is ok. But you're still checking for .check in atleast one place.

Arrays can be used to develop more efficient code. You are simulating an array with the $variable1 convention.

It's as I supspected.
The PHP script isn't echoing JavaScript strings, it's echoing variables.
Or atleast that's what the browser will think when encountering:
Here's how it should look:
Fix that by doing:
