currency problem

[tanviet12]

Hi all,

My Hostbill default currency is VND (Vietnam Dong, 21000 VND = 1 $). When i use Paypal for checkout, the amount ( VND) doesn't convert to $ and it wrong. I try create additional currencies  USD (In Setting --> General Setting --> Additional Currencies) but I cannot assign rate with value 0.000047619 ( 1 VND = 0.000047619 USD). I found type of colum rate in table hb_currencies is decimal(10,4) .

mysql> describe hb_currencies;
