Hello,
see attached file.
First, consider re-defining your range names not to span whole columns. This is pointless if you want to use them for data validation. I've re-defined them to include just the occupied rows. Any empty row you include in the range name will render the data validation useless, because the user can enter any value.
I've then copied the exact text from column C in Sheet3 to the table headers in Sheet1, to make a lookup possible.
Now, on Sheet2, this formula will lookup the desired fare:
cheers,
