Need a routine to find value in Access table and post value on sheet in appropriate cell

Excel 2003
Access 2003
"C:\DATA\MyGreen.mdb"
Table called "tblGreen"
2 fields
1- tblSku - text -100
2. tblGreenSku - text -100


"C:\DATA\Green.xls"
I have a sheet "tblFinal"
Headers in Row 1 always
Column A could at anytime contain any number of rows

ColumnA   ColumnB          ColumnC
Sku           comments       Green Sku
1A123       YES
2ER45       YES
6TY78        MAYBE
4R5T6       COULD BE

WHAT I NEED:

I need a sub routine to :
Take each  Value in ColumnA
See if it exists in  table "tblGreen"
in field tblSku - text -100
if it does  post the value in
"tblGreenSku" in ColumnC

If not fille the cell with "No Green"


EXAMPLE DATA IN :
tblGreen"
tblSku   tblGreenSku
1A123  2AW34
2ER45  4RE56
4R5T6  4RT51
etc....



RESULT:

Sku           comments        Green Sku
1A123       YES                  2AW34
