 * Hi! Why is there an issue when I’m trying to check out with paypal. Here’s my
   code:
 * _NUMBER 1: _ Quantity of orders
    _CALCULATION 1:_ {number-1}*2964 _CALCULATION
   2:_ {calculation-1}*.12 _CALCULATION 3:_ ({calculation-1}+{calculation-2})*0.04058272
   + 15.6087408 _CALCULATION 4:_ {calculation-1}+{calculation-2}+{calculation-3}
 * I’m checking out with paypal using the CALCULATION 4, but whenever I’m testing
   it, there’s an error says: **Error! Invalid payment amount!**
 * How can I fix the issue?
 * I need this ASAP.
 * Thanks,
    Marj

 * Hi [@marjenjavi](https://wordpress.org/support/users/marjenjavi/)
 * Sorry to hear you are having this issue.
 * Can you please try the code shared in this thread?

 * There is a reported issue if the final result is more than 1.000, the shared 
   code should prevent it.
 * Let us know the result you got.
