Ok this is an issue which I know can be fixed I dont know how yet seems what must happen
MYR sent to USD then sent to Paypal
USD sent back to Mysite converted USD to MYR and then received and process complete.
First Case Paypal users used funds in Paypal account
Yesterday User checked out Paypal using paypal funds available checked out fine posted to zen with out a single issue. The funds were in here account.
Today checkout for express Checkout is broke
User Tries to do this with express checkout and it gives
ALERT: PayPal Express Checkout Error (10413)
10413 Transaction refused because of an invalid argument. See additional
error messages for details. - The totals of the cart item amounts do not
match order amounts.
What is the difference in the conversion stream from MYR to USD then payapl Process USD sends USD to site. Site converts the USD to MYR using the same formula and constant for conversion Posts it MYR and Completes Transaction
