How to withdraw on Paypal checkout page-and your custom text field in working with IPN?

Please help. Work with Paypal via IPN. In my view there is a c shape parameters for the Paypal button. What is required? After we clicked "Buy now" and we moved to the Paypal checkout page, I want to see my custom preset field. A simple textfield c label. You want the client to enter the data I needed on the page checkout page.
Here on this page:

Is it possible? Maybe this is configurable in the settings of the business account?

Here's an example of what I try. Alas, I do not see the field:

the button code can't be changed

try to connect Marchant API for their fields, but it's too easy
I thought that maybe there are some settings at the button, allowing you to transfer input that you want to render on the checkout page. Or at least somewhere in the admin panel of the business account to create, then to display. - Yadir commented on June 3rd 19 at 19:41
, payment systems slightly paranoiac. this is normal.
therefore, they do not allow you to the payment page got che to implement. - jarret commented on June 3rd 19 at 19:44
it's sad. Now we have to convince the client that he is-only field next to the button to do, and not on checkout page. - Yadir commented on June 3rd 19 at 19:47
not have to convince anyone.
these are the RULES of the PAYMENT SYSTEM.
so to say.

if th his problem with the payment system.
not with you. - jarret commented on June 3rd 19 at 19:50
