Excel: locate value in one list & copy

Hello,
I need some help with Exel. I have two lists:
List one contains two coulmns: ID numbers and age.
List two contains also two coulms: ID (some from list 1) and their running time in a race.
I want to have in List one an addtional (third) coulmn - RunTime with the matching runtime for the IDs. If ID in list one does not have a corresponding runtime in List two a "." value will be assigned.

Can someone help me with this task?
Many thanks in advance,

Tut
