It depends on the method attribute of your HTML form how the variables get passed to your PHP script.

In this case, it sounds like page1.php does not have any side effect, and just passes on values, so the form on page1.php should use method=get, and the code of page2.php that reads these fields can find them in $_GET.

The Submit button on page2.php (presumably) does have side effects on the server side, so it should use method=post, which you can read back from $_POST on the server side.

Also, have a look at the HTML source of page2.php after filling out the first page, to see if the values are passed correctly.
