You will see a column for the new "City" category to the right of
the column for the "Fuel Economy" measure. The cells in a
category column are shown in green. The cells in the "Fuel

can’t change them directly.

option again. Repeat the process you did for the "City" category,
using the name "Highway" and the units "mpg". You should now
see the columns for two categories to the left of the column for the

the cell you want and type in the number.
