I have a spread sheet that has 2 drop down boxes in and I want to create a third one that Is the result of the first two.

E4 has the options
Voice
Data
Reshot
Simo

I4 has the options of
1
3
12
18
24

And for example each each result would be bank1, bank2 ie
voice and 1 = bank 1
Voice and 3 = bank 2
Voice and 12 = bank 3
Voice and 18 = bank 4
Voice and 24= bank 5
Data and 1 = bank 6

Etc

Cheers
