Hi @ohjeez,
Thanks for sharing your question with the Community!
@retention gave some great potential workarounds to include the information you want in forms. If installing a Javascript event listener to your form still interests you, but you don’t feel confident installing this custom code yourself, I would encourage you to reach out to a Klaviyo Partner for any custom coding needs you might have.
Additionally, I can definitely submit including dynamic values in our forms as a feature request, however at this time, forms do not accept any dynamic value or data at the present. For this same reason, Dynamic Coupon Codes not available for forms, if you want to include a coupon in a form it has to be a Static Coupon.
These fellow users in the Community had similar questions about using dynamic data in forms:
