Hey 
just updating this thread since it’s from an older setup.
With the current Funnelish version (V2), this specific issue is no longer related to OTO button configuration or legacy setups.
If you’re seeing a message like “Your credit card was declined”, this is now almost always coming directly from the payment provider (e.g., Stripe, PayPal, NMI, etc.), not from Funnelish itself.
To learn more about this, feel free to check out this helpful guide: Credit Card Declined Error on Checkout
