Need Help from FluentForms Members Here

FF support says they do not have a way to hide the Credit Card field on subscriptions (I have four subscription options to choose from) when a coupon is applied and the amount equals to $0. I have been told by support that this is normal, but my experience with other forms is that the CC field can be hidden when the price is $0. I can do this easily with GF without writing any code.

FF support told me that I can write some custom JS to hide the CC field if the amount is $0 or explain in an HTML field to ignore the CC field if the amount is $0. For one, that is a bad user experience to have to explain this and secondly, I do not write JS.

Overview: I have four yearly subscriptions - $20, $30, $50, $100 and the coupon is for $20 off. If the first one is chosen and the coupon is applied, it should be $0. I don't want the CC field to show when it is $0.

Has anyone here done this already with their site that has the JS code? Any other ideas? It has to be a subscription. Thank you in advance.
