i have two sheets, one has a list of names and corresponding amounts.
the other sheet contains a second list of names and amounts in the
next two columns. Some of the names are appearing in the first list. i
need to create a macro which will scan through the two sheets, and if
the same name is in the two list then i want those names to appear on
the third sheet and in the next three columns i want the amounts from
the first list and the amounts from the second and third columns of
the second sheet.

The following assumes data starts in A2 on all sheets (there is a
header row). If this isn't true, you will need to modify the code a
bit.

Sub CopyMatches()
Dim c1 As Range
Dim c2 As Range
Dim c3 As Range
Dim rng1 As Range
Dim rng2 As Range
Dim iRow As Long

With Worksheets("Sheet1")
Set rng1 = .Range(.Cells(2, 1), .Cells(Rows.Count, 1).End(xlUp))
End With
With Worksheets("Sheet2")
Set rng2 = .Range(.Cells(2, 1), .Cells(Rows.Count, 1).End(xlUp))
End With
With Worksheets("Sheet3")
.Range("A2:D30").Clear
Set c3 = .Range("A2")
End With
For Each c1 In rng1
For Each c2 In rng2
If c1.Value = c2.Value Then
iRow = iRow + 1
c1.Resize(1, 2).Copy Destination:=c3(iRow)
c2.Offset(0, 1).Resize(1, 2).Copy
Destination:=c3(iRow).Offset(0, 2)
End If
Next c2
Next c1
End Sub
