How to use a Click/List box to bring up values

Hi all

I am new to this, so i hope someone can help

I have attached an excel sheet which i am trying to get data from. on the RASCI sheet has Job Titles, and numbers below the job titles, which will tell me what actions is under what Job title.

On sheet 2

This is where i would need the information
i have put a list box in which gives me the job title and then what i would like is the actions to go under R,A,S,C and I.

If anyone knows how to do this it would help a lot.
