TOPIC: Incorrectly formatted item amount in Paypal

When I try to make a payment using Paypal it directs to a page with the following message:

The link you have used to enter the PayPal system contains an incorrectly formatted item amount.

Having read other posts on this, I am using the DOT not the COMMA seperator and the payemnts are in Pounds Sterling.

I'm using version 2.7.1b does anyone else seem to be getting this error, want to make sure it's not me doing something silly before submitting a support ticket.

Thanks
