commission

hello there, I have been using this plugin to manage my affiliates but there seems a problem that I couldn’t find a solution for. I have a coupon for one product but the plugin is calculating commission based on the cart value regardless of the coupon.
for example, I have a coupon discount for X product but in the cart, there are X Y Z products, where the customer has used the coupon and got a discount for the product X. the commission is calculated for the total amount of cart value rather than calculating just the value of X price where the coupon has been applied. How can we solve this? please let me know
