First off I want to say thank you for developing this component.  This has the exact functionality that I needed for my latest hairbrained idea!    

I am however having an interesting issue.  I have set this up with paypal sandbox and it works flawlessly, down to the last bit.  However when I run it through my live paypal account it says the transactionw is successful and returns me to the website where i see the success message, but no credits are added to the account and the log holds an email error message: "Not Primary PayPal email: emailAddress@Here".  I am fairly certain that this is simply something screwy in my paypal account settings but I am not sure which settings and where at.  Does anyone know where this issue could be being caused in the paypal account system?

Note:  The email it returns as bad is one of my emails but it is not my paypal account email.  However I cannot find that email setup anywhere in the account profile/settings.

Thanks in advance to whomever can show me how stupid I am being and remind me where / what to set for this.

Well the confusing thing was that I only had one email on the account.  I finally figured it out though, one of my wifes old accounts had a couple of emails on it (one of which was the one that kep showing up in the logs) and I am not sure how but it was connecting the two accounts through the emails somehow.  As soon as I removed all of my emails from her account it started working great.  Thanks for the reply and the component.
