I have it currently all on one page, but it isn't quite what I was after

Any help would be appreciated!
Hi Aslan:
Keeping it all on one page (one script) is fine -- no problems with that.
Here's the technique I use.
$step = isset($__POST ['step']) ? $__POST ['step'] :1;
if($step == 1)
{
// do the first page stuff (Symptoms)
// with a POST form that has an <input type="hidden" name="step" value="1">
}
if($step == 2)
{
// do the second page stuff ( Troubleshooting questions)
// with a POST form that has an <input type="hidden" name="step" value="2">
}
if($step == 3)
{
// do the third page stuff (Answer to problem)
// with a POST form that has an <input type="hidden" name="step" value="3">
}
If you want to pass variables between pages (trips from client to the
server nad back again), you have four options, namely: 1)
writing/reading a file; 2) writing/reading a database entry; 3)
passing via a POST/GET; 4) or using SESSIONS.
For most things, I prefer using POST/GET and/or SESSIONS. Try this format:
$var1 = isset($_POST['var1']) ? $_POST['var1'] : null;
$var2 = isset($_SESSION['var2']) ? $_SESSION['var2'] : null;
That's the way I pass data between client and server.
However, what you are describing sounds a bit like this:

With this example, I'm not passing anything to the server --
everything is kept client-side and is quick.
If interested, all the code is there.
Cheers,
