Incorrect quantities pass to PayPal

Hi,

I’ve 3 different types of tickets I am planning to sell. User should be able to purchase any or all combination of different tickets.

Currently if user only pick 1 qty for ticket type 1 and set 0 for other types, plugin still send the quantity as “1” to PayPal for not selected ticket types.

Ex:
Ticket 1: $10
Ticket 2: $20
Ticket 3: $30

User want to buy two Ticket 1. (which would cost $20)
Once user submits the form, PayPal charges ($20 + $20 + $30). $70 in total.

Somehow plugin doesn’t respect the “0” quantities. Is there any work around for this problem?

Thanks
