Salesforce Marketing Cloud > Landing Pages > Insert Error Message for Duplicate Registration on a Landing Page...
I want to make my landing page return a message saying that the record is already registered when the visitor tries to add an existing record.
In my research I found this article that seems to solve such a problem.
But it wasn’t clear in the article where I should insert the AMPScript code?
Would it be in the middle of the HTML code of the submit button on the landing page form?
If so, where in the HTML code should I insert these AMPScript code?
Would anyone know how to answer me?
