Help with Data valadation List

[StubbornOx]

I am not sure how to ask this question but here goes. I am trying to create a form where when I select an item for a drop down box (data validation List) It automatically selects the appropriate data and places it into the next column. For example, if I select payroll in the list it automatically puts 073-119-043, but If i select travel it puts 073-306-871 in the next column.
