Thank you Gilles for all your help.

I am in United States. I am using the Paypal Module not the email.

In one post I saw that we will need add some more parameters if we are using the Paypal Payment System.

Do you have any idea what those parameters are?  I filled out everything that was on the settings for the Store module.

I contacted Paypal below is the their  response:

Research conducted using username pptest using p001 product code. I received the same page presented in your initial screenshot.  Looking at the logs for the backend of that account, I see no API calls hitting, or at least authenticating, on that account. Another thing I am noticing is that the button to send the transaction to PayPal is not a PayPal-hosted button.

PayPal requires that you use Express Checkout button images hosted on PayPal's secure servers, rather than hosting copies of these images on your own servers. Also, using the buttons on the PayPal servers eliminates the need for you to maintain them yourself. If the buttons are updated, the new buttons will appear automatically in your application. Using out-of-date PayPal buttons could reduce customer confidence in your PayPal deployment.

I am at the point if I cannot figure this I will proably not use this module. But if you can help me I will be grateful.

Thanks again,

Tareq

Hi Tareq,

The response from PayPal suggest you use Express Checkout. But the Store module use Website Payments Standard! There is 6 different payments mode in the US (Express Checkout, Website Payments Standard, Website Payments Pro, PayPal Mobile Checkout, PayFlow Link, PayFlow Pro), but only 2 in France and other countries (Express Checkout, Website Payments Standard), except in the UK where you can use Website Payments Pro.

The buttons are not hosted in your web site, they are called from PayPal (setting: PayPal Button URL inside Store Admin). In the Store Admin module, you must select PayPalProvider for the Gateway setting. Because you live in the US, the default PayPal provider settings can be used. You must have a Business PayPal Account and enter the email you use for create this account in the PayPal ID setting. That's all! For testing, check the Use PayPal Sandbox setting. While using sandbox, normaly you must be login to PayPal with you business account and use a false client account created at PayPal for simulate your client. Read chapter 8 and 9 of Website Payments Standard Integration Guide for details.
