IDs of elements don't work like the names of input elements. If you have two elements with the same ID, only one of them will be used by JavaScript. (The last one, I believe.)

So you need to rethink your approach.
A simple workaround is to have the elements pass their value into the function as a parameter and have the function use that.

Meaning, you would have to change both the radio buttons to:

 Help with Code Tags 
 html Syntax (Toggle Plain Text) 
<input type="radio" name="radio" value="xxxx" onclick="chgtx2(this.value);" />
<input type="radio" name="radio" value="xxxx" onclick="chgtx2(this.value);" />

And the JavaScript function to something like:

 Help with Code Tags 
 javascript Syntax (Toggle Plain Text) 
<script language="javascript">
        function chgtx2(value)
        {
            if(value==9.95)
            {
                window.document.form.hidden1.value=10;
            }
            else
            {
                window.document.form.hidden1.value=20;
            }
        }
        </script>
<script language="javascript">
        function chgtx2(value)
        {
            if(value==9.95)
            {
                window.document.form.hidden1.value=10;
            }
            else
            {
                window.document.form.hidden1.value=20;
            }
        }
        </script>

That should do the trick.

And to have the keyword count changed based on the radio button selection, change the JavaScript to:

 Help with Code Tags 
 javascript Syntax (Toggle Plain Text) 
if(count != parseInt(window.document.form.hidden1.value) - 1) {
    alert("Only "+ window.document.form.hidden1.value +" keywords are allowed.");
    document.form.textarea1.focus();
    return false;
}
else {
    return true;
}
if(count != parseInt(window.document.form.hidden1.value) - 1) {
    alert("Only "+ window.document.form.hidden1.value +" keywords are allowed.");
    document.form.textarea1.focus();
    return false;
}
else {
    return true;
}

And you could add the PHP code into that, like so:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?php
$error = false; // Used later to print the error message
 
if(isset($_POST['a'])) {
    if(substr_count(trim($_POST['a'], ','), ',') != intval($_POST['hidden1']) - 1) {
        $error = true;
    }
    else
    {
        // Process your keywords here
    }
}
?>
<?php
$error = false; // Used later to print the error message

if(isset($_POST['a'])) {
    if(substr_count(trim($_POST['a'], ','), ',') != intval($_POST['hidden1']) - 1) {
        $error = true;
    }
    else
    {
        // Process your keywords here
    }
}
?>

Which I highly recommend, seeing as JavaScript is not really a reliable validation method.

Please do not ask for help in a PM. Use the forums.
And use [code] tags!

Ditto.

Client side validation is only ever useful to prevent MOST users from sending wrong data to the server MOST of the time. It will not prevent certain individuals from bypassing these checks (intentionally or otherwise) and you can guarantee that at some point "tainted data" will reach your server. Anyone with a webpage can send data via 'dummy form' to your form handling page.
Nasties could be in the shape of SQL/script injection - not nice.

Thats simply because javascript can perform only client side validation... a nasty user can disable javascript for his/her browser and can easily surpass ur validation script.
But php validation is done at server end which is impossible for a user to disable coz its out of his/her reach.
The reason we use javascript is to do some basic validations to avoid user sending data to server and then getting rejected from server validation which will eat up much of server's resources.
In a nutshell javascript can enhance ur validation process but can never replace server side validation(PHP in this case).
Hope i made my point clear.
