Unable to take information from PayPal payment page to site.

[prem2k]

I have signed up with PayPal standard payment (free one) as the payment gateway on my website.  The site content is generated dynamically from database and therefore the prices and conditions carries to PayPal gateway screen for processing payment.

Buyers add items to the shopping cart and can choose to continue shopping followed by checkout and payment on PayPal screen.

After payment: page display two links '1. Return to the site and 2. Check PayPal account'

Processed information is send back to the site only if ‘1. Return to the site’ is clicked. 

Is there any way I can take the information from the PayPal screen and post it back to my site for stock maintenance, records, and to send invoices?

Thanks for any help you can give.

In order to update your end, ever if the customer does not return to your site would be to use PayPal's IPN feature.  You can find out more via the following links:
