Paypal Usa & Canada - Invalid Total Amount (10426) With Different Currencies

[radiumdude]

Hi,

 

My default currency is USD and with the paypal USA & Canada module the customer can checkout with paypal without any issues.

 

I recently added the currencies GBP and EUR to the store, and update the conversion rate with via Prestashop.

 

The problem is, when a customer checks out with Paypal express (haven't tried standard payments as I don't use it) in either EUR or GBP, I get error 10426, 'The total amount is invalid'. 

 

It seems that something is wrong with the formatting of the number that is being sent to Paypal, since if I set the exchange rate to 1 then the customer can checkout with EUR/GBP, although obviously at the wrong price.

 

 

 

Does anyone know a fix for this? 

 

Thanks
