Paypal - Charging each order TWICE!

[fruitbat]

Calling all you oscommerce gurus out there,

 

Thanks to the wonderful contribution from dynamo effects (BIG BIG THANKYOU), I've managed to install paypal pro but there's a slight hitch - each and every time I run an order test (live on authorisation so I can void it since my sandbox login never turned up) paypal takes the payment twice and I can see two copies of the order in my paypal login. At first I thought it was connected with quantities but that doesn't seem to be the case, I've tested multiple numbers of products and within that quantities and it's still just doubling it.

 

The site (unfinished) is - http://www.copybits.co.uk/catalog - it's my first one so doesn't look like some of the others yet!!

 

My php skills aren't good enough to figure this out myself :(

 

If anyone can point me in the right direction it would be a great help.

 

Dynamo Effects - once I've got some orders coming in I'd be happy to make a donation for all your good works and efforts :)

 

Thanks

 

Jo
