Using find within macro

Hello,

I have a list of first and last names of employees (Sheet1). Some of these employees have adjusted work schedules which are listed in a different sheet (Sheet2).
Now I would like to add a comment to the last names of sheet1 so you don't have to switch to sheet2 to find out when those employees work.

Sheet1 is made up like this:
Column A starting at row 8 contains the last names.
Column B starting at row 8 contains the first names.

Sheet2 is made up like this:
Column A starting at row 8 contains the last names.
Column B starting at row 8 contains the first names.
Column D starting at row 8 contains the hours for Monday.
Column E starting at row 8 contains the hours for Tuesday.
Column F starting at row 8 contains the hours for Wednesday.
Column G starting at row 8 contains the hours for Thursday.
Column H starting at row 8 contains the hours for Friday.

Since the list of employees isn't fixed I would like a macro which does the following:
Loop through the first and last names of sheet1 and compare it to the names of sheet2.
If a match is found add a comment to the cell which contains the last name of sheet1.
The comment should look like this:
"Ma:" & Cells(???rownumber???, "D").Value & Chr(10) & "Di:" & Cells(???rownumber???, "E").Value & Chr(10) & "Wo:" & Cells(???rownumber???, "F").Value & Chr(10) & "Do:" & Cells(???rownumber???, "G").Value & Chr(10) & "Vr:" & Cells(???rownumber???, "H").Value

Hopefully someone can help me especially with the finding/looping part of my query.

Best regards,
Trowa
