if 3 comobos are inter-related, below is the approach normally taken.

1. On screen_load, only fill combo1
2. If select any item in combo1, then only fill combo2
3. If select any item in combo2, then only fill combo3
4. If combo1 changed to a new different type, then reset combo2 by refill it and combo3 would make blank till select any item in newly filled combo2
