Hey Darren,

Many thanks for this great package, works really well and exactly what I needed :)

One point that is probably due to my misunderstanding of the whole PayPal process or due to a strange error in PayPal.

In my Set-up button I selected to take customers to a thank you URL

I tested the payment and it went through perfect, I then clicked the PayPal "Return to merchant' button which sent me back to the success page within Umbraco. This for some reason seemed to send *another* IPN request which means this transaction got put into Umbraco again (my success page has NO code in it)

This caused an error as the package then recreated a bunch of fields which already existed (address_city, option_selection1,subscr_id etc.) 

This obviously caused the content node to error as there were duplicate properties.

I manually deleted the duplicate properties and all was fine.

Putting another transaction through AND going to the success page caused a duplicate entry again however this time the duplicate fields were NOT added.

It now works perfect for me as I re-created the button and took out the ability to go to the success page.

Hope this post helps someone else out and i'd be interested to know what I was doing incorrectly,

Again, many thanks for your great package! 

Cheers

Rich
