Select ActionSelect AllTry It<%
Dim bookTypes(7) 'creates first array
bookTypes(0)="Classic"
bookTypes(1)="Information Books"
bookTypes(2)="Fantasy"
bookTypes(3)="Mystery"
bookTypes(4)="Poetry"
bookTypes(5)="Humor"
bookTypes(6)="Biography"

Dim arrCars(4) 'creates second array
arrCars(0)="BMW"
arrCars(1)="Mercedes"
arrCars(2)="Audi"
arrCars(3)="Bentley"

Call createList(bookTypes) 'takes bookTypes array as an argument
Call createList(arrcars) 'takes arrCars array as an argument
