referntial integrity issue with two tables cant delete a record
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
So I am trying to delete a record from customers table. I would assume it's a referential integrity issue, however I don't really see what is wrong with it. Could anyone shed some light? Please and Thanks. Error Message below
