Secure paypal form submition

Question

I am trying to make a payment system which is using a paypal form. The problem is, that people can click "View details of element" in their browser, and edit the prize and such in the html.

How do I prevent this? I thought about having the form on another site which instantly submits it, but I want to avoid using Javascript since some people dosen't have it turned on.

You can do this by INSTANT PAYMENT NOTIFICATION which is a a message service that notifies you of events related to PayPal transactions. You can use IPN messages to automate back-office and administrative functions, such as fulfilling orders, tracking customers, and providing status and other transaction-related information.

The second option would be using a BUTTON API which helps you in making encrypted buttons.

Please have a look here and here for the more info.
