Paypal integration, email template problem

Hi,

I have QLM 12 and I succeeded in integrating Paypal. I have a Paypal button and when I click, I can do payment on Paypal. The key is created in the data base. But in the email received, paypal variables are replaced but not QLM variables. I use the QLM original template. Here is the received email:

Here is the string parameters: &is_productid=1&is_majorversion=0&is_minorversion=8&is_features=0:15&is_licensemodel=subscription&is_maintplan=true&is_expduration=365&is_quantity=3&is_emailtemplate=Paypal.NewSubscription&is_emailtemplate_renew=Paypal.RenewSubscription&is_emailtemplate_cancel=Paypal.CancelSubscription

In the log there are three errors:

Exception: There are multiple root elements. Line 1, position 21.

Error parsing duration . Error: StartIndex cannot be less than zero.
Parameter name: startIndex

Error extracting is_expduration. Input string was not in a correct format.

Spend a day trying to figure out why.

Any suggestion
