~The form itself~
Say you bring up a web page and it is called Page A. Page A is a web page that has a Text field with a submit button. When you type in some text into the text field and hit submit, you post the content in the text field to PAGE B and you (the user) goes to a PAGE C. Page A will then be included into Page D. When you visit Page A a second time the TextArea is populated with the content you submitted the last time. When the text field is changed again it removes the old content and saves the new content.
My question is how do i make the Text box on Page A be populated with the content on PAGE B.
