Match 2 Columns Across Two Sheets & Copy Rows Of Matches

I would like to match column data in a source spreadsheet to column data in a target sheet. If a match is found, I would like to copy the corresponding row range from the source sheet to a separate, third sheet. For values where no match in found in the a target sheet, I would color the unmatched cell in the target sheet red. If a match was found, the cells would be colored green. The data in the Source sheet is in column A, while the Data in the Target sheet is in Column T. The data will be pased in the third sheet in Column T preserving original formats

I have this code, gleaned from several postings on this forum that somewhat works. The problem is that I get false mismatches (i.e. some cells get colored red even when there is a match and the data got copied to the third sheet) even though there are no duplicates. I have made sure that the formats are identical in both Target and Source sheets to try to fix this. Also, I don't want to cut the entire row , but just copy and paste a row range onto a third sheet. The column and row ranges are variable. I am attaching a file.!!

Sub CutRows()
Dim i As Long, k As Long, n As Variant, r As Range
Application. ScreenUpdating = False
With Sheets("Source")
Set r = Range(.Cells(1, 9), .Cells(65536, 6).End(xlUp))
End With
k = 0
i = 6
While Not IsEmpty(Sheets("Target").Cells(i, 20))
n = Application.Match(Sheets("Target").Cells(i, 20).Value, r, 0)
If IsNumeric(n) Then
Sheets("Target").Cells(i, 20).Interior.ColorIndex = 35
k = k + 1
Sheets("Source").Rows(n).Cut Sheets("Sheet3").Rows(k)
Else
Sheets("Target").Cells(i, 20).Interior.ColorIndex = 3
End If
i = i + 1
Wend
Application.CutCopyMode = False
Application.ScreenUpdating = True
End Sub
