store credit and discount makes paypal $0 and break

Hi.

Hopefully the image attached correctly below. I have a zencart with a discount policy for one category only, everything works fine normally with the checkout process. I have a 10% discount setup for totals of $200 and 15% for $300.

One issue im having though is for example if I add $185 store credit for a customer, they order $202 in total, they get $20 discount then which takes them to $182, enough store credit now to complete cover the order. Whats happening though is the paypal module still is being injected but with a remain balance of $0, which is not possible in paypal, so people need to make it $1 or it just loops.

This is only happening when the discount brings the total down to under their store credit. If they only ordered say $190 worth of product, discount applied and they had say $195 I store credit, the balance would again say $0 but the paypal module isn't shown it realizes there is $0 balance and the order completes no problems.

Any assistance appreciated.

Where did this "store credit" feature come from?

I'm guessing it's what's breaking the normal operation.

Hi DrByte,

Im using the quantity_discount module by thesoftwareguy, that's all installed and working normally? everything there is calculated correctly

Don't use the store credit setting in Quantity Discounts. That feature isn't built out.
