HI There,

I need your help with this issue:

2 FADI ON3 6
3 BRIAN ON4 5
4 MOHN ON9 2
5 ALEX ON6 7

sheet2

A B C
1 JHON ON1 2
2 BRIAN ON4 7
3 ALEX ON6 7
4 FADI ON3 8

I want sheet3 to be:
A B C
1 JHON ON1 2
2 FADI ON3 6
3 FADI ON3 8
4 BRIAN ON4 5
5 BRIAN ON4 7
6 MOHN ON9 2
7 ALEX ON6 7


I want macro to compare betwwen sheet1 and sheet2,
John & Alex were in both and same value in C col, copy to sheet three

Fadi & Brian were in both but different value in C col, copy row to sheet3 and fill the row copied from sheet2 with "green for example"

Mohn was only in sheet1, copy to sheet3

I have attached the file

Sorry being my question is long, but really I need help

Thanks in advance
