passing variables between php forms

Hi sorry to annoy you AGAIN, but i cant seem to get it working.... i think its something to do with the order that i put things in: #end of html and start of php script <?php #Take the Variables from enterdetails.php that are posted from an html form $firstname=$_POST['txtFirstName']; $lastname=$_POST['txtLastName']; $email=$_POST['txtEmail']; $quantity=$_POST['txtJars']; $order_value=sprintf('%.2f', floatval($_POST['txtJars'])*7.0); echo '<INPUT type="hidden" name="testvar" value="'.$order_value.'" />'; ?>php # end of php script back into html Are your details correct? <tr> <td valign="top" colspan="3" align="center"><form action="confirm.php" method="post"><input type="Submit" name="submit" value="Yes"></form></td> </tr> <tr> <td valign="top" colspan="3" align="center"><form action="updateaddress.php" method="post"><input type="submit" value="No&nbsp;"></form></td> </tr> </font> If i put the echo or INPUT type outside of the php script this works, but obviously just returns a string '.$quantity.' and not waht the variable $quantity holds. This is extremely confusing. How do i get this php variable to be passed to the HTML so it can be posted I thought the way i have it the echo would make the variable testvar available to the browser, and then i would be able to retrieve it by $_POST[testvar]; or $_POST[$testvar]; in either the confirm.php or updateaddress.php that the html posts to? Yet again thanks in advance for any help. Confused Cheers From baldey_uk
