checkout_success coupon amount deduction

[luxor]

please note i have an older version of ccgv installed on my store.

 

also i am refering to coupon code and not a gift voucher.

 

 

I have a need to modify a successful check out to see if a coupon code was used for the purchase. I then need to take the total order amount from the order and subract this from the coupon amount.

 

if the coupon code is less then the coupon amount, then I will leave the amount left for that coupon available in the db.

 

 

for example: order is $500.00 , and coupon is for $1000.00

 

$1000.00 - $500.00 , then coupon value becomes $500.00.

 

if anyone knows if these variables are available on checkout_success It would be very helpful to let me know them. also if they are not available on the the success page, then how would i pass them?

 

thanks so much for help.
