session_register not working with multiple forms

Forgive me - I am new at this. I have a muti-form site where I need a variable from one form to be visible across many forms. For instance, in form 3 I get variable ptype and need to see it in form 4. In each of my forms my "action" is to call myphpcode.php - which performs tasks based on the inputs of the form just used. I am trying to use session_register - but it just doesn't seem to make ptype visible throughout all my forms... Below is an example of what I did. I apologize for the overload of code - I am just at my wits end. Thanks for any help !!!

//form1.php
<?php
session_start();
?>

<html>

<title>blabla </title>

register_globals needs to be on for session_register() to work. You should use $_SESSION['ptype'] instead.

register_globals is ON and I tried $_SESSION['ptype'] and it didn't work either.

This

echo $ptype; // DO NOT SEE ptype HERE!!!
Needs to be
echo $_SESSION['ptype'];

If you edit your first post and wrap the code for each file in separate php code tags so that we can see which code belongs to each file, you will have a better chance of someone seeing what you are trying to accomplish.

The session_register() and related functions have been depreciated since 22-Apr-2002 and should not be used. You should also not be writing any new code that relies on register_globals being on.

By having a form field name the same as a variable and having register_globals on, causes them to refer to the same storage and the last source in the variables_order "EGPCS" wins and will overwrite the other. Either turn register globals off (as php.net recommends) or use unique variable names for everything.

The only valid method="..." for forms are "post" and "get". Your method="link" is invalid and only does not work because browsers ignore a lot of invalid tags and parameters.

Okay - I made all my methods equal to "post", got rid of session_register and replaced it with $_SESSION and I still am having problems seeing ptype in form 4 ... I broke out each section for better viewing ... any ideas ?? Thanks for all the help so far!!
