How can I get the CloudPage not to go to the 500 error page if I am using InsertData() but the data was already existing in the Data Extension? It works the first time if it doesn't exist, but it the error appears if someone goes to the CloudPage a second time.
%%[VAR @Id, @FirstName, @LastName, @Address, @City, @State, @Zip, @Country, @InsertCountSET @Id = RequestParameter("Id")SET @FirstName = RequestParameter("FirstName")SET @LastName = RequestParameter("LastName")SET @Address = RequestParameter("Address")SET @City = RequestParameter("City")SET @State = RequestParameter("State")SET @Zip = RequestParameter("Zip")SET @Country = RequestParameter("Country")SET InsertData("Member_Address","Id",@Id,"FirstName",@FirstName,"LastName",@LastName,"Address",@Address,"City",@City,"State",@State,"Zip",@Zip,"Country",@Country)]%%
