Pay Pal buttons where to paste the code?

Hello,
I have two ZCs and I am using payment option Paypal with link only on bigger shop with many items. I created Paypal buttons for small one as Paypal people told me I have to set up another Paypal account or create more expensive type of Paypal-for example Checkout Express. Or create buttons and paste codes to every item.

Well, I did it as it is easy. But when I read all their guides they are telling PASTE TO YOUR WEBSITE only.

Can you tell me what php site or place in ZC will recommend me where I can paste my codes? To Paypal php? Or where?To payment?
Thanks.

I'm not sure I understand the question, but you don't need to paste anything into Zencart to use Paypal. The module is built-in.

Also, there's no dfference in cost between Paypal Standard and Express.

you do not need to creatre paypal buttons NOR do you need to setup a different paypal account,

Zen Cart is designed to run multiple sites from 1 paypal account

just turn on the IPN module in zencart and put in the primary email address used for paypal.com

zencart will send the correct information and return information for each store seperately

If it is possible, it will be great but I tried and was confused.
I am speaking now about 1.3.8 ZC and Paypal IPN Website Standart.
I have to put link to my website.
It tells me in Payment module
set your Instant Payment Notification Preferences URL to:
http://website/ipn_main_handler.php
(If another URL is already used, you may leave it alone.)
This is Ok, until Website Payments Preferences .It say it sets your Automatic Return URL to:
http://website/index.php?main_page=checkout_process
But it allows me only put one link to one website.So how?This thing I don't understand.

You don't need to change it if something valid is already there. As long as you have something in there, Zen Cart will be able to automatically override that for transactions coming from your store.
Just don't leave it blank.

I did it, thanks, I was confused from one link. I used my email for Paypal and token, all. Easy.
