hi
use condtional formating.
select a2.
on the menubar...
format > conditional formating
formula is.....=$A$2="X"....pick your color.
copy B2 and paste accross the row as far as you want.(whole row?)
Apply conditional formatting to all the cells that you want to change (the
entire row). Use the "Formula is" option in the first box. See Excel's help
documents for how to use the "Formula is" method of conditional formatting.
Best of luck.
