INDEX/MATCH Not Working?

Hello all,

Why does my formula in cell J3 work, but cell K3 is not working? I would expect the returned value in cell K3 to be "Toyota Innovia (Manual)".

It's possible that I am simply not using these formulae correctly. What I am trying to achieve is the table on the right displaying the cheapest option (company/vehicle/cost) for different numbers of guests and durations. If you could suggest a more elegant solution, I would be all ears.

Many thanks,
Peter.
