Many forms in one php file

Hi I want to create a single php file which will be able to display multiple html forms. Like this: Form1 -> Form2 -> Form3. After the user completes and submits Form1, the script will process it and display a different form. etc... I am new to php, I would need some detailed instructions, or point me to an opensource php script which already does that so that I can analyse it. -- NSK http://portal.wikinerds.org
