Thanks and Regards, Cyrus Chan

What I do is store all the fields in $_SESSION variables, so when you go back to the page, if they filled that particular field out, it should show what they have already completed. ------------------ <?php session_start(); if ($_POST["submitted"] == 1) { $_SESSION["field1"] = $_POST["something"]; $_SESSION["field2"] = $_POST["pizza"]; } ?> <form action="wherever.php" method="post"> <input type="text" name="something" value="<? echo $_SESSION["field1"]; ?>"/> <input type="text" name="pizza" value="<? echo $_SESSION["field2"]; ?>"/> <input type="submit" value="GO"/> <input type="hidden" name="submitted" value="1"/> </form> ------------------ So, there's no need to use javascript or to actually "go back." You can just "redirect" to that page and have it "remember" the variables. To redirect back to it, use header("location: http://mysite.com/wherever.php"); It is not *always* necessary to use the absolute path to indicate that particular page in the header() function, but it doesn't hurt. Sorry if I have rambled on or confused you - it's late and I'm sleepy. Good luck with that. ~Philip
