For 5.5 why are u multiplying by 2 and not dividing because isn't the KMTRAVEL for the total trip and since we are only concerned with the return would we not divide by 2
If a box pops up asking for a value then it means you have misspelt one if the field names incorrectly. Either an s is missing or there is a space etc. Double check the spelling of any field that you have typed out.
