How to do multiple select with ActiveCell - excel

Question

I'm trying to make multiple selections from Sheet2. The value is from the same column but different rows (thinking if using ActiveCell.Offset(1,0) will be feasible).
My code takes the value from an ActiveCell select and runs a macro compares it to another sheet (Sheet10) with some information to copy and paste in a target sheet (Sheet5).
The following is the code that I have right now.
a = Sheet10.Cells(Rows.Count, 1).End(xlUp).Row
c = Sheet2.Cells(Rows.Count, 5).End(xlUp).Row
For Each cell In Range(ActiveCell, ActiveCell.Offset(1, 0))
For i = 2 To a 'from Row 1 to the last row of "DMP"
Debug.Print ("i = " & i)
If cell.Value = Sheet10.Cells(i, 1).Value Then 'if selected cell matches (i,1) of "Sheet10 (DMP)"
Debug.Print ("ActiveCell =" & ActiveCell.Value)
For k = 1 To 20 'from Column 1 to Column 20
Debug.Print ("k = " & k)
For r = 1 To c 'from Row 1 to the last row of "Sheet 2(LightOn SKU)"
Debug.Print ("r = " & r)
If Sheet10.Cells(i, k).Value = Sheet2.Cells(r, 4).Value Then 'if value of (i,k) of "Sheet10 (DMP)" = (r,4) of "Sheet2 (LightOn SKU)"
Sheet2.Range("A" & r & ":G" & r).Copy
Sheet5.Activate
b = Sheet5.Cells(Rows.Count, 1).End(xlUp).Row
Sheet5.Cells(b + 1, 1).Select
ActiveSheet.Paste
Range("A" & r & ":L" & r).Borders.Color = vbBlack
End If
Next
Next
End If
Next
Next
Right now, it's running on an endless loop.

Still Unclear
Sub ACCopy2()
Dim a As Long
Dim c As Long
Dim r As Long
Dim i As Long
Dim k As Integer
Dim b As Long
a = Sheet10.Cells(Rows.Count, 1).End(xlUp).Row
c = Sheet2.Cells(Rows.Count, 5).End(xlUp).Row
For r = 1 To c ' from Row 1 to the last row of "Sheet 2(LightOn SKU)"
Debug.Print ("r = " & r)
For i = 2 To a ' from Row 1 to the last row of "DMP"
Debug.Print ("i = " & i)
' if selected cell matches (i,1) of "Sheet10 (DMP)"
If Sheet2.Cells(r, 1).Value = Sheet10.Cells(i, 1).Value Then
Debug.Print ("Sheet2 =" & Sheet2.Cells(r, 1).Value)
For k = 1 To 20 ' from Column 1 to Column 20
Debug.Print ("k = " & k)
' if value of (i,k) of "Sheet10 (DMP)" = (r,4) of
' "Sheet2 (LightOn SKU)"
If Sheet10.Cells(i, k).Value = Sheet2.Cells(r, 4).Value Then
With Sheet5
b = Sheet5.Cells(Rows.Count, 1).End(xlUp).Row
Sheet2.Range("A" & r & ":G" & r).Copy .Cells(b + 1, 1)
.Range("A" & r & ":L" & r).Borders.Color = vbBlack
End With
End If
Next
End If

End Sub
