Help linking data to a dropdown/combo box

Hi

I've been tasked with updating trainee files, and what I would like to do is create a dropdown/combo/list box (whichever works most easily with what I am trying to accomplish) that has a list of employees. On the page, dates of their training change with employee (although the criteria does not).

For example, if I select Peter, the page would say "Survival training: Oct 31"

I then select Paul, it says "Survival training: Nov 2"

I know how to get the names in the box, but when I select them, obviously nothing happens. What is the next step?

I'm kind of new to advanced excel functions, so bear with me!
