Table Lookup for variables.

I believe what I am looking to do is sometimes called a "table lookup".  

I want to create a 2-column table for variables.  I then want to set up  a data entry field (code1).  When the student enters something into this data entry field Storyline would evaluate code1 against a table.  If code1 appears in column A then variable description1 would be set to the corresponding item in column B.

for instance:

Column A    Column B

BB01            Blue Boat

WB01           White Boat

GB01           Green Boat

If the student enters "BB01" into the data entry field I can display  "Blue Boat" on the screen.  Otherwise I think I have to manually create a trigger for every item that would be in Column A.

Thank you for taking the time to read this post.
