Your order page should have the following code

<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="your-paypal-id-here">
<input type="hidden" name="item_name" value="your-product-description-here">
<input type="hidden" name="item_number" value="your-product-id-here">
<input type="hidden" name="amount" value="transaction-amount-here">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="invoice" value="invoice-id-here">
<input type="hidden" name="return" value="url-of-ppok.pl?invoice=invoice-id-here">
<input type="hidden" name="cancel_return" value="url-of-ppok.pl?cancel=1">
<input type="submit" value="Pay now">
</form>

Note 1: You should use unique invoice id. Invoice ids used as values for invoice and return inputs must be the same. Use ssippinv.pl script in order to generate unique invoice number and ensure values for invoice and return inputs match. Here is a sample order form using ssippinv.pl:

<form method="post" action="http://www.paypal.com/cgi-bin/webscr">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="your-paypal-id-here">
<input type="hidden" name="item_name" value="your-product-description-herer">
<input type="hidden" name="item_number" value="your-product-id-here">
<input type="hidden" name="amount" value="transaction-amount-here">
<input type="hidden" name="no_shipping" value="1">

<input type="hidden" name="cancel_return" value="url-of-ppok.pl?cancel=1">
<input type="submit" value="Pay now">
</form>

Note 2: You can use custom input to pass additional parameters, use

<input type="hidden" name="custom" value="login/existing-account-id/password">

for auto login for existing customers or

<input type="hidden" name="custom" value="autologin">

to use Auto Accounts feature.
