The fix at
http://www.gjcwebdesign.com/configuration-paypal-payment-module-virtuemart.html works fine for sorting out the various currency issues and a disclaimer place on the store site explaining the slight difference between the paypal total and the virtuemart total due to the different exchange rates used between ECB and Paypal allows it to be used. The problem i have is if you checkout using the primary store currency using the above paypal script i get the following error from paypal:
The amount received was: 40.19 GBP.
It should be: 40.2 GBP.
If i revert back to the original paypal code this is not the case so somewhere in the new paypal script their is a rounding error but i cannot find it - It only seams to do this when the primary currency - in my case £ is used when checking out as the other orders in Euros work fine with no error.
Has anyone else had this problem and if so is there a fix for it?
ps here is my code:
