Greetings once again,

I have a workbook which has one sheet that contains data from a
statistical
database. Another sheet is said workbook contains a DIR listing of the Raw
data files from which the data is sent to the database. (See the example
below.)

I would like to use the raw data file name in column E 'left(Ex,10)' from
the DIR sheet and determine if that string exists in the SPC sheet column
G.
If the string does not exist in column G, I want to BOLD the Ex cell in
the
DIR sheet.

I wish I knew a programmer that I could sit down with to build this code,
but I ask for your help to get me through this task.

Regards and thanks in advance

Hal in Detroit
