hello,

I found a tutorial script that works for me but it doesn't seem to work well with radio buttons. I'm hoping someone could have a look at that script and help me get it working with the radiobutton.

the selection carrie over to the process.php script but cant seem to process the selection.
need 2 things:
1 process the selection.
2. in the event user enters incorrect information somewhere else i like to be able to go back to the form with the users original radio button selection. eg. Name: <input type="text" name="name" value="<?php echo $name; ?>" > <br />

any help you can give me would be greatly appreciated.



index.php
PHP Code:
<body>
<h3>Form testing</h3>
<?php echo $errorString?>
<br />
<form name="formprocess" method="POST" action="process.php">
    Name: <input type="text" name="name" value="<?php echo $name?>" > <br />
    eMail: <input type="text" name="email" value="<?php echo $email?>" > <br />
    Birthday:<input type="text" name="birthday" value="<?php echo $birthday?>" /><br />
    <br />
    <p> <input type="radio" name="radiobutton" value="1"> OptionOne </p>
    <p> <input type="radio" name="radiobutton" value="2"> OptionTwo </p>
    <p> <input type="radio" name="radiobutton" value="3"> OptionThree</p>
    
    <input type="submit" name="formSubmit" value="Submit">
</form>
