One way is toto create an enumerator with all the variables related to vip.
BUT, as vince one mentioned to me for a question i had related to a house system he told me that.

Quote:

Username should only appear once in the database. While it is technically possible to set up a foreign key relation with a text type field, it is discouraged to do so because string comparison is obviously much slower than integer comparison. Especially for varchar fields where length is not fixed.

Connect 2 different tables of your database.. Don't use username everywhere . Create relation views. If this is so difficult then create an enumerator which will have all VIP variables. and instead of using account variables use VIP one.
