[RESOLVED] Donate2 And Promo Codes

Hey all, 

I'm seeking advice on setting up promo codes via donate2 forms for our upcoming benefit reading event. We want to offer complimentary tickets without adding a free button. I've tried setting the promocode price at 0, adding the correct performance ID and price type ID but I'm having trouble implementing it. I've also included:  <promotext></promotext> into the text of the payment button I wanted to have a promo code attached to and no luck. Has anyone successfully done this in donate2 before? Any insights would be greatly appreciated.


I've checked both this: https://help.donate2.com/article/596-promo-code-inserts-text and https://help.donate2.com/article/589-promo-code-used-max but am not sure these help answer my question. 

Thanks in advance
