Hi, I want someone to write an html script. Page 1- My customer enter some personal information like name and any number e.g. 123456 i have given to him and Click on the paypal button and makes the payment and is redirected to page 2 Page 2 - He gets a secret code after some calculation based on the number provided at page 1 i.e. 123456 What I want? 1. Script should be very simple. No third party script included. 2. I should be able myself to make any changes regarding calculation criteria. 3. Full usage and resell rights. What I Don't want? 1. Nobody should be able to view the calculation method. 2. Nobody can be able to visit at page 2 directly WITHOUT Payment. I think it is so simple. Thanks!@ Please let me know if anyone can complete it.
