What you ask is possible. but you should tell us more precisely what and how you want it done.
The code below runs for 100 rows, compares corresponding cells of sheet 1 to sheet 2 and if 2 or more cells match it copies the value in G column of sheet 2 to K column of sheet 1.
for a = 1 to 100
if cells(a,1) = worksheets("sheet2").cells(a,1)
b = b + 1
if b > = 2 then
cells(a,11) = worksheets("sheet2").cells(a,7)
you have to change the cell numbers to suit your needs
