Let’s say that your page name is “login” and you’ve set a custom state at page level called “plan” of type text.
When you’re navigating to a different page, there is check box “Send more parameters to page”, check this box.

Now you need to define a key, let’s call it “plantype” for simplicity. Put the value of this key as “login’s plan’s value”.
On the next page, you can now use URL parameters to extract the plantype.
