Affiliates Gravity form issue [duplicated]

Hi

I am using affiliates pro plugin…. I want $1 referral Per form submission on cash payment and want 3% commission on pay online but when i select “Enable the Affiliates integration for this form?” then we get commission and when i select “base amount ” then we get $1 but we want both $1 per form submission on cash payment and 3% commission on pay online… How can i do it ?

Thank You.
