I also used the test card no of pay pal doc with security No 123(I am not sure about their security no).But same thing occurred. Anybody please help me…. I am totally stack with that problem.

Thanks and regards

That error simply means that you are trying to use a variable before it's been initialized (I know that is stating the obvious).  All you need to do is setup for debugging and you'll be able to see exactly where the error is occurring and that will help you figure things out.  Open your project in Visual Studio, select  Debug - Exceptions.  Then click on the checkbox under "Thrown" for the "Common Language Runtime Exceptions", then press F5 to run your site.  Then run through the steps to reproduce your error.  The IDE will now break in the source code on the exact line of code that is failing, not just at the point that the exception is caught.  I know this doesn't exactly answer your question, but at least you'll be able to figure out which line is failing and go on from there.  Let me know if you need more help.

Did you ever get this figured out?  I have the exact problem.

 Did you seup the payment provider in the admin section

 Hello everyone,

                    Please help me.Even i am having the same problem. I have set up shipping, tax and payment providers(paypal pro). Here are the exception details.I am struggling really hard to get out of it, can you help me out.

While debugging i noticed i am getting this error in PAYPAL SERVICE.CS  at line 

 expressCheckoutPaymentRequestDetails.Token = order.ExtendedProperties[PAYPAL_TOKEN].ToString();

when the extended properties are returned  by this method in

ORDER.CS

public ExtendedProperties ExtendedProperties {
      get {
        if(_extendedProperties == null) {
          if(!string.IsNullOrEmpty(this.AdditionalProperties)) {
            _extendedProperties = new ExtendedProperties().NewFromXml(this.AdditionalProperties) as ExtendedProperties;
          }
          else {
            _extendedProperties = new ExtendedProperties();
          }
        }
        return _extendedProperties;
      }
    }

Any suggestions would be greatly appreciated. I am working on my local mahine. Is Trustlevel a problem?

Thanks in advance

If you are getting the error on this line:

order.ExtendedProperties[PAYPAL_TOKEN].ToString();

Then the PAYPAL_TOKEN does not exist in the order's ExtendedProperties collection. Are you sure that your configuration on the PayPal side of things is correct?  Also, you might want to find out where in the code the token gets set and see why it is not getting set.  Do you use the IPNHandler or the PDTHandler?

 Tim

Thankyou for your reply Tim, I am using PDT Handler. Any suggestions with that would be of great help.

Thanks in advance

I'd just like to clarify that when using PayPal you need to have both the PDT and IPN configured. It is not an option to enable 1 and not the other. If you do this, you will almost certainly end up with orders that are not properly processed.
