We've built a register form inside WFFM with a custom save action. The custom save action tries to create a new user with an exterior service. However sometimes the e-mail they use to register, already exists in the exterior service.
When a user registers with an account that's already in use, we would like to display a message at the top where the usual error message that says: "There was a problem while trying to register your account".
Is this possible?
