VLOOKUP Problem

Hi,

I've got a problem with VLOOKUP.

In one worksheet I have pilotes with the race number and the club and in a second worksheet I have the results.

So when I type the race number in my second worksheet the name of the pilot should be returned but that's not the case for number 0 and 1

If I understood well VLOOKUP is not able to work with a 0 (zero) but I really need this 0 and how could this problem be solved

Many thanks for your help
