The radio button and text are contained within a <form></form> tag set.
The <form> tag will have either method="GET" or method="POST"

If method="GET", you can read back the values using:
$foo = $_GET['foo'] where 'foo' is the name of your radio selector or
text field.

If method="POST", you can read back the values using:
$foo = $_POST['foo'];

Re: retaiing values when resubmitting a page

inside the tag for the textarea, the value attribute should be set to a
snippet of php which echo's (or prints) the value of the posted
variables. If nothing has been submitted, then nothing will be echoed,
and the box will appear empty. if something was submitted, it will be
echoed back into the box. A similar idea applies to radio and
checkboxes, but it's SLIGHTLY more dificult because you have to
determine (using if conditionals) which button it should be set to.

thanks
I found a solution. posted below incase anyone else is interested

at top of page
session_start() ;
$_SESSION['mytextbox'] = trim($_POST['mytextbox']);
$_SESSION['myradiobutton'] = trim($_POST['myradiobutton']);

for the textbox
input name="mytextbox " type="text" value="<?php echo
$_SESSION['mytextbox'];?>"

for the radiobutton
input <?php if (!(strcmp($_SES SION['myradiobutton'],"1"))) {echo "CHECKED";}
?> name="myradiobu tton" type="radio" value="yourchec kedvaluehere"
